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>
