Added plip config along with other related diazotheme configs.

plip-13355.cfg gets diazotheme.startup to give you a basic collection
of startup themes.
diazotheme-frameworks.cfg gets all the diazotheme.startup,
diazotheme.frameworks and diazotheme.bootswatch so you can get the idea
of the parent theming.
th-code.cfg gets the masters and has the mothballed separate themes for
frameworks commented out.
