Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added two new tree functions, get_title and get_parent and finished the OS/2 folder browser. Will be porting to Unix soon. Windows tree functions need to be completed. Will do that tomorrow.
