Add pre-save and post-save hooks

Browse Source 
This adds support for hooks which are executed before/after saving
calcurse data. Hooks can be placed under hooks/pre-save and
hooks/post-save in the data directory and need to be executable.

Potential use cases include:

* Automatically commit any changes to the data files using a VCS.
* Automatically sync with some sever component on data file changes.
