templater: ignore orig/rej files
If your mercurial/templates/ directory is dirty, then the template system would
otherwise import duplicate templates from the .orig files and potentially try to
parse .rej files.
Since editing/reverting these templates isn't an unexpected action, and since
they're in .hgignore, it's best that the template system know to skip them."
