Add support for --bold (and --underline) to the __bobthefish_start_segment function.

 * Show the closest parent repo if $PWD is in both an hg and git repo.
 * Only find the repo root once per SCM, not two or three times :)

 * Inline a one-line method that's called one place
 * Make sure __bobthecow_virtualenv_python_version doesn't fail if python isn't a symlink.
 * Add a visual segment indicator after python version glyph.

remove some additional unnecessary complication.

- Bookmarks and command/directory history functions implemented
- Function to edit commandline with $EDITOR
- Faster git parser

[bak] Fix tests

Add mercurial support for bobthefish

This reverts commit 8b94f572f170510f8fb0e2f51a657e267dc86241.

Add TODO to do this right :P

This makes it easier (possible?) to distinguish between hg and git repos at a glance.

Add local-config plugin.

Support per-user, per-host, and per-platform custom configuration files.

Stops theme breaking in root directory
