kiss: add repository update hook

Browse Source 
The package manager will look for an executable called 'update' in the
repository's root directory. If a KISS repository is one of many
children in a git repository, the hook will only be called once.

This hook is run /after/ a repository has been updated by the package
manager. If your repository is not using git, the hook is run immediately.

If the hook fails (exits non-zero), the package manager will also fail.
Hooks can be written in any language. No arguments are given to the executable.

Closes #174
