Rewrite steeef theme using git-info

This uses the verbose mode to be able to display indexed, unindexed and
untracked files indicators. This is the last theme left to be migrated
to git-info, and the first one to use its verbose mode.

Originally, the theme also supported svn via vcs_info. The svn support
is lost in this rewrite. Maybe if a new svn-info module is introduced to
Zim...
