Trac importer improvements (by Mat Trudel):
* better support for wiki internal links (still not perfect, but much improved) * support for unordered lists * support for most of trac's highlighting tags (underline, bold, etc) * import progress dots now flush to stdout on every dot, so the import doesn't look frozen * support for migration of multiple trac instances into a single Redmine install (as separate projects) git-svn-id: http://redmine.rubyforge.org/svn/trunk@931 e93f8b46-1217-0410-a6f0-8f06a7374b81
