feat: Added subcommand to retry commit

A new subcommand can be used to retry a commit message. By putting the
keyword `retry` as the first argument after `gitcommit` then you will
fastforward and skip the steps of filling out the individual fields. The
full commit message will be loaded from the last time you confirmed a
commit message.

Resolves #49
