SSP-818 Convert html msg to plain text.

This is a cherry-pick of 31f99aa5e2cb5c619d92775adfe3f820d11efa91.
Did have some conflicts, mostly having to do with 000024.xml already
having been created in the target branch.

A little bit concerned about upcoming Liquibase issues since
000024.xml is going to be run in different relative order in a
1.2.0 vs a 2.0.x deploy.
SSP-856 Cleanup markup in existing Journal Entry comments.

Only worked on a MSSQL script b/c we have no real-world PG deployments.
