Make version bumping more flexible.

Some of my old metadata.rb files have versions in the form of "x.y" and
not "x.y.z", however Chef::CookbookLoader returns them in the "x.y.z" form.

This means that the gsub in update_metadata didn't work. This change
makes it a bit more flexible.

Updated 'bump' example for accuracy.
Fixes spork-bump when cookbook_path contains cookbook

Fixes an issue where cookbook_path is incorrectly stripped
of all occurances of the cookbook name from the cookbook_path.

Example: attempting to bump a cookbook named `chef` located at
`~/Sites/paperlesspost/paperless-chef/chef` previously failed because
cookbook_path was evaluated as `~/Sites/paperlesspost/paperless-/`.
Now the regex will only match occurances at the end of the string
and the cookbook_path will be `~/Sites/paperlesspost/paperless-chef/`.
Fixes cookbook_path that contains cookbook name in git_add

Fixes regex in git_add that strips cookbook name from cookbook_path
to only remove the last occurance of #{cookbook}.
