DefaultData largely rewritten with unittest, SDL input event handling completed with unittest, changes to Init threading. Init threads now catch own exceptions. Doc: assigned some inputID devisions. Added support for remaining SDL events. Input axes' output is now stored with a short instead of a real. Input unittest written (for SDL event handling). Rewrote most of mde.mergetag.defaultdata using generic programming to generate read & write rules for all types. As a direct result, defaultdata can now write properly. DefaultData unittest written (also provides testing for mergetag read/write). Moved mde.text.parse/format to tango.scrapple.text.convert.parseTo/parseFrom with many changes. committer: Diggory Hardy <diggory.hardy@gmail.com>

This is mostly just a list of potential minor issues noticed while coding but not seen worth throwing an error about.

Overall:

read.d:
	Support partially loading a file.
	parseSection(): as mentioned at end of function
	formatting errors could be more informative; in particular say where the error is
	No binary support.

write.d:
	Threading support?
	There is currently no way to specify the base in which numbers are written (in text form).

parse.d:
	Doesn't support cent/ucent.

format.d:
	No support for cent/ucent or ulong where val > long.max.
