Redmine

This modification is Easy and enhances the integration between RedMine and SVN: A new field in the issue that represents
the "Revision Number" from the SVN repository, that when filled creates a link from the issue directly to
the revision.
For example: a Developer fixes a bug, and in the moment he is editing the issue to "fixed" or others status,
he puts the number of the revision from the SVN into this new field. When other developer acess this same issue, he
could see exactly the code written by the person who fixed the issue, because that would be the diff associated with
the revision.
