[PATCH guilt] Handles slashes in branch names

[Eric Lesh <eclesh@ucla.edu>]

When a branch name has a slash and autotagging is enabled, guilt barfs
when updating the stack tags.  Escape the branch name in the tags to
allow this to work.

Also allow guilt to create the patches directory for these branches.
