Subject: Warp back to 5578.  Sorry for the lost changes, please re-apply. 
 Reason: 5579 is a complete disaster.

Not only does it change tons of files to switch to a new and non-working (it doesn't parse my ini files, at least) ini parser, it also reshuffles a lot of code and removes a plugin. The latter part is fine, but doing these two major switches in one revision, one of which is broken, is completely unacceptable. I said to merge tiny changes, not massive reworkings.
