First step in two-part process to rename directories to kallithea.
This first step is to change all references in the files where they refer
to the old directory name.

config: added example uwsgi configuration with auto-scaling
workers mode.

Allow RhodeCode maintainers to specify a custom bug tracker.

This allows people who maintain large RhodeCode installations to setup their
own bug tracker and respond to requests against their specific installation.
The maintainer is then free to forward problems with RhodeCode to the
canonical issue tracker on bitbucket.

If the config option "bugtracker" is present, its value will be used with the
"Report a bug" button. If left blank, this disables the button. If no value is
present, then the default is used. This is so that the new config option
doesn't break installations of RhodeCode upgrading to a newer version and to
allow easier installation for the common use case.

Fill session cookie secret with random generated app_uuid.
By default this setup is much more secure since it uses
SignedCookies instead of plain ones

added initial_repo_scan flag for controll if repo scaning should be performed on every startup.

config: rename options to show_revision_number and show_sha_length

'sha_show_numeric_rev' had nothing to do with the sha value.

The revision numbers are kind of native to Mercurial and there they are known
as 'revision numbers'.

'sha_len' was very short and didn't clarify that it only controlled what was shown.

These settings are currently only used in the changelog, but they should be used everywhere.
