Redmine

I spent some time on the Mercurial adapter. I made two changes that I purpose to you :

• I wrote a new revisions method that parses changesets with only one call to the hg program. I use a template that makes hg output the changelog in XML. I put the templates in extra/mercurial. There are two templates because the templating syntaxe changed a bit with Mercurial 1.0. I did not make benchmarks but I think it's slightly faster than the actual method. This new method also fetch informations about copied files.
• I made changes on the entries method to be able to browse the repository at any revision. The actual method cannot list directories that do not exist in the present revision.

I tested my code on Linux with Mercurial 0.9.5 and on Windows with Mercurial 1.0.
