Remove stale cache

[ericadamski]

Currently when a commit-with is run it caches a commit template to use when committing with the same person again. If a new version is released that adds/removes from that file it should get overwritten

Possible solution

A possible way to do this is to add some meta data to each template about when it was created and what version was used to create it. Then we can have rules like, if you are older than n days or the CLI version is different re-write the file.

Could make use of commander options, eg.

commit-with -f|--force ericadamski

which force writes the template file

This has been started with f98ea44

Still need to parse the meta that is now being written. At least the cache can be busted manually using -f or --force
