admin: fix 'Settings > Visual' form validation after commit 574218777086

Commit 574218777086 introduced a setting for 'SSH Clone URL' in 'Admin >
Settings > Visual' and placed it under a check 'if c.ssh_enabled', which
means that the corresponding form field is not present when SSH is not
enabled.
In this case, when trying to save the form (changing any or none setting),
form validation reports an error 'Missing value' without much detail. At the
top of the HTML document, even before the opening HTML tag, we can see:

<!-- for: clone_ssh_tmpl -->
<span class="error-message">Missing value</span><br />


Fix this problem by adding a hidden form field for clone_ssh_tmpl, with the
current value from the database, in case SSH is not enabled.

ssh: show ssh URL on summary page

Original change has been heavily modified by Mads Kiilerich.

less: use .label and .label-* style instead of custom .*tag

This reduces the code and makes it more consistent.

Visualy this results in bold texts (which in case of small fonts is easier to read)
and a bit more padding left and right.

For a proper spacing, this requires to remove whitespaces before and after
the texts inside the labels.

Since the name changed from tag to label, also rename the variables and functions.

style: drop form-horizontal - our style is much closer to plain Bootstrap forms

form-horizontal is made for grid markup. It give form-groups a negative margin
to break out of the grid ... but the way we use it for settings, we have to do
weird things to undo that. The default styling for forms is much closer to what
we want. It looks ok without our custom styling and is easier to style to our
style.

If we want grid markup with form-horizontal, it would be correct to
re-introduce both at once.

admin: clean-up of Gravatar and IP in user profile headers

Move things around and use Bootstrap compatible markup.

The user IP will rarely be relevant - especially not on the admin pages; the IP
configuration there is more for other user's IP. It might however be somewhat
relevant for a (non-admin) user to know his own IP. There is no obvious place
to show that - it doesn't really fit in as a part of the user profile. Anyway,
just show it under Show Permissions.

style: introduce Bootstrap markup for list-unstyled

Based on work by Dominik Ruf.

templates: replace invalid metatag attributes with data attributes

(We could also use plain classes ... but stick to the plan ...)

settings: fix saving of visual settings of page size

After 19f15cde2cdb it was no longer to save page_size because formfill didn't
match. Back out a part of that changeset.

style: consistently use label markup wrapping around input elements

The 'for="..."' markup is error prone.

style: add missing 'form-control' markup

Based on work by Dominik Ruf.

style: drop 'checkboxes' class inside 'form-group'

Temporarily, just apply styling to div inside form-group. Also, 'radios' is gone.

Based on work by Dominik Ruf.

style: drop 'input' class inside 'form-group'

As long as we use the old styling, just apply styling to div inside form-group.

Based on work by Dominik Ruf.

style: quite-but-not-entirely trivial cleanup of "settings, visual"

Providing a cleaner baseline for Bootstrap.

style: refactor form label styling to prepare for Bootstrap and get rid of wrapping with 'label' class

Based on work by Dominik Ruf.

style: put all admin form buttons in a form-group, as our future Bootstrap likes it

Based on work by Dominik Ruf.

style: in preparation for Bootstrap, refactor to use Bootstrap compatible form class names

Based on work by Dominik Ruf.

style: in preparation for bootstrap, use bootstrap compatible button class names

Give all buttons a styling (default, success, danger, warning) and rename the sizes to sm and xs.

This is a subset of a bigger changeset. The subset was extracted by Mads Kiilerich, mostly by:

sed -i \
-e 's,btn btn-small,btn btn-default btn-sm,g' \
-e 's,btn btn-mini,btn btn-default btn-xs,g' \
-e 's,btn-default btn-\(xs\|sm\) btn-\(success\|danger\|warning\),btn-\2 btn-\1,g' \
-e 's,class_="btn",class_="btn btn-default",g' \
`hg mani`

spelling: fix inappropriate use of title case

These are not titles or labels, and should not be title cased.

spelling: consistent capitalization of URL

Change Url / url into URL.
Additionally, convert the sole use of 'Uri' to URL.

Second step in two-part process to rename directories.
This is the actual directory rename.
