should have Tango-styled icons

[Daniel Schierbeck]

bzr-gtk needs icons for the following concepts:

 - A branch
 - A repository of branches
 - A single revision
 - A set of changes (diff)
 - A conflict between two branches

These actions also require new icons:

 - Commit a set of changes
 - Revert a set of changes
 - Pulling changes from another branch
 - Pushing changes to another branch
 - Merging two branches
 - Resolving a conflict between two branches

The following file icons would also come in handy:

 - A file that has been modified
 - A file that has been removed from the branch
 - A file that has been added to the branch
 - A file with conflicts
