Mepo

Fixed

- Fixed bug for CI systems

Added

- Add ability to see fixture (see release notes for more)

Added

- Add `mepo-cd.csh`

Fixed

- Fixes for `whereis` and `diff`

Fixed

- Updates to allow mepo clones to be moved (106)
- A bit of nicety on `mepo status` for detatched HEAD states
- Adds `mepo-cd.zsh` as I couldn't figure out how to get the bash script to work in zsh

Fixed

- Bug fixes for `mepo save`
- The command would save the new yaml file in `pwd` rather than at the "root" directory where the original was. This was a bit confusing, so the command now saves at root level
- `mepo save` did not handle hashes well. There is no reason it couldn't save to a hash, but it labeled it as a `branch` in the yaml file which, while not broken, was in consistent.
