good progress on limiting post form display.
got help from istvan and joco on the 'right'-est way to do this, given the time available and existing codebase.
bulk of my commits today were ancillary code clean up... the real stuff is working locally, but still has a few minor bugs, so still need to do due diligence to squash them before pushing live.
- pop js confirm only when post content has been changed
- resolve minor inconsistencies in open/close behavior
- test again
