#33 Enhance IP Revision History

Hello,

Currently the IP revision history in version 4.3.2 only tracks who/when made a change.

An enhancement is if it would also record the data that existed in the IP record before it was modified.

Workarounds:
1. Backup/Restore database and load data into another application instance.
2. Dump IP database into a text file nightly and grep through that for the data.
