TracMercurial: missing changeset error raise a !LookupError, catch them.

TracMercurial: add multiple repository support to the property renderer.

This is done in a backward compatible way, i.e. it works well fine with [milestone:0.11].

TracMercurial: add support for MQ and other extensions.

In order to add mq support (useful for getting the patch names listed as tags), one has to specify a .hgrc file in the TracIni, then the normal `[extensions]` section in that .hgrc file.

trac.ini:
{{{
[hg]
hgrc = trac.hgrc
}}}

trac.hgrc (as it was specified with a relative name, the file is located in TRAC_ENV/conf, next to the trac.ini file):
{{{
[extensions]
hgext.mq =
}}}

Add traditional Chinese, used in Taiwan.

Allow translation of error pages.

Add locale attribute to the Mock instances.

Use a proper NullTranslations instance instead of the class.
This should fix errors of this kind:

TypeError: unbound method ugettext() must be called with NullTranslations
instance as first argument (got str instance instead)

See: #5958
Fix supplied by Shun-ichi Goto

Various clean ups.

Massive update of all translation files with the latest template file.

Add file for Greek translations.
