No generation changes from v1.1, however code is now cleaner, and some bug/crash fixes have been applied (particular focus has been around the api, in advance of a add on mod I'm working on)  Please report any bugs you my find.

Details:

 - Fix to JSON parsing if an generation module is missing from the string use the default
 - Allow api to register additional presets (added to the list)
 - don't show hover help when over buttons on customization screen
 - add api to get pre-calculated region elements
 - fix a crash editing the preset string
 - fix a crash if an addon adds a module with an odd number of parameters (all the built in have been even so
   this was not yet a problem
 - Cleanup/Review existing code.

tested on mc 1.11 and 1.11.2
