Plugin: Add a system for logging events related to pledges and contributors (#54)

Uses action hooks to capture relevant events as log entries on a per-pledge basis. This provides a running history of a pledge and can be used as an audit log if questions arise about changes to a pledge or there are weird bugs.

Fixes #39
