this makes the "theme changes lost" issue raise its head.

i think we've hammered out what's going on, though.
reproduction steps:
1- make several changes in the Theme Script
2- observe them on TCP
3- open theme tweaker
4- make a change (to selected midi note background, for example)
5- enjoy your changes, then quit reaper
6- re-open reaper.
7- ISSUE: your theme tweaker changes have been lost, TCP reverts to default
8- re-load the default script. NOTE- TCP goes back to your tweak
9- now make and select some midi notes. ISSUE: the theme tweaker changes are now lost.
10- rinse and repeat
