In progress:

To do:
*	Write Input unittests; remove untested notes
*	Why doesn't input.config filtering via headers "Configs" work?
*	add options support; in particular for whether or not to use threads (and adjust Init to use this).
*	OutOfMemoryException is not currently checked for − it should be at least in critical places (use high-level catching of all errors?).
*	Sensitivity adjustments. From es_a_out:
        /+ FIXME: revise.
        + I can't see any point using HALF_RANGE here, since it should really be used dependant on
        + the device attached, not the axis. Also what about adjusted range like X3's throttle?
        +
        + Sensitivity: is this the right place to adjust it? For things like throttle where the
        + ends of the interval must remain fixed, multiplying cannot be used to adjust and adjusting
        + the curve via a power function doesn't seem to be what we want. For things where the
        + end points needn't remain fixed, multiplying seems the right thing to do, but cannot be
        + done here since we don't know the end points can be changed.

        if (conf & SENSITIVITY) a = s.pop();
        /+ When a global sensitivity is available (possibly only use if it's enabled)...
        else a = axis.sensitivity;
        y = sign(y) * pow(abs(y), a);		// sensitivity adjustment by a +/

Done (for git log message):
*	Init threads now catch own exceptions.
*	Assigned some inputID devisions.
*	add remaining SDL event support
*	Rewrote most of mde.mergetag.defaultdata using generic programming to generate read & write rules for all types. As a result, defaultdata can now write properly.
*	Axis output now stored with short instead of real.
*	Input unittest
*       Moved mde/text to scrapple
*	DefaultData unittest. Then commit.
