html: put 'use strict' on separate lines

use.py:
import re
import sys
for fn in sys.argv[1:]:
with open(fn) as f:
s = f.read()
s = re.sub(r'''(<script>)('use strict';)\n( *)''', r'''\1\n\3\2\n\3''', s)
with open(fn, 'w') as f:
f.write(s)

python use.py $(hg loc 'kallithea/templates/**.html')

js: use strict ... and fix the problems it points out

"use strict" gives stricter checks, both statically and at runtime. The
strictness tightens up the code and prevents some kinds of problems.

The <script> tag addition might not be pretty, but has consistently been added
with:

sed -i 's,<script>$,&'"'"'use strict'"'"';,g' `hg loc '*.html'`

js: omit redundant type="text/javascript"

We already used plain '<script>' in several places.

https://www.w3.org/TR/html52/semantics-scripting.html#element-attrdef-script-type :
"Authors should omit the attribute, instead of redundantly giving a JavaScript
MIME type."

template: use Bootstrap tooltips and popover instead of handmade tooltips

Based on work from Andrew Shadura <andrew@shadura.me>.

Further modified by Mads Kiilerich.

show_changeset_tooltip is merged into tooltip_activate.

style: rename div.table to Bootstrap .panel-body

Based on work by Dominik Ruf.

style: introduce "clearfix" class where the Bootstrap migration will need it

Based on work by Dominik Ruf.

style: in preparation for bootstrap, replace kallithea title class with bootstrap compatible panel-heading

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

sed -i 's,<div class="title\>,<div class="panel-heading,g' `hg mani`
sed -i 's,\<div\.title\>,div.panel-heading,g' kallithea/public/css/style.css

style: in preparation for bootstrap, replace kallithea box with bootstrap compatible panel

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

sed -i \
-e 's,<div\(.*\) class="box",<div\1 class="panel panel-primary",g' \
`hg mani`

templates: only bind pager event handlers once - avoid "leaks" and repeated page loads

Summary page ended up hammering the server and when pages were loaded one time
extra for each paging click.

Just moving javascript code from the data template (where it would be re-run on
each paging) and to the main page template.

controllers: don't pass rendered templates in context variables

Some controllers used the followifng pattern:
- render a data template into a context variable
- for partial (ajax) requests, return the contents of this variable
- for full-page requests, render the full page, which expands the value of
the context variable

Instead, avoid context variables let the controller simply render the full or partial page, and let
the full page template include the partial page.

Remove this context variable for templating and use render exclusively.
From templates, use %include instead of context variables.

This in line with the suggestions in the Pylons documentation:
http://pylons-webframework.readthedocs.org/en/latest/helpers.html#partial-updates-with-ajax

templates: move site branding in page title to base template

Instead of repeating the same three lines in each and every template, move
it to the base template.

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