Allow the 'revert' option in Git Gui to operate on untracked files, deleting them

My development environment sometimes makes automatic changes that I don't want to keep. In some cases, this involves new files being added that I don't want to commit or keep. I have typically had to explicitly delete those files externally to Git Gui, and I want to be able to just select those newly-created untracked files and "revert" them into oblivion.

This change updates the revert_helper function to check for untracked files as well as changes, and then any changes to be reverted and untracked files are handled by independent blocks of code. The user is prompted independently for untracked files, since the underlying action is fundamentally different (rm -f). If after deleting untracked files, the directory containing them becomes empty, then the directory is removed as well.

This introduces new strings in index.tcl. I have been told that there is a separate process whereby the translations get updated.
