Removed extra math

The elapsed's get cancelled in the numerator and denominator anyway. Probably doesn't jitter when followLerp = 0, but I didn't check for it.
Comparing methods with == doesn't work 

The correct way seems to be with Reflect.compareMethods
Add limit on touch movement for triggering button events
Update camera flash sprite position when camera position is set
Make FlxMath.bound have optional params instead of requiring nulls.
FlxColor fix to make a 0 FlxColor not equal null
Better fix for FlxColor equality ensuring (null:Null<FlxColor>) == null on all platforms (Thanks @mrcdk!)
Merge pull request #1223 from SergioB/patch-3

Comparing methods with == doesn't work
FlxSignal#getHandler(): only use Reflect.compareMethods() when necessary (#1223)
FlxBitmapTextField#draw(): revert to latest working version, closes #1218
FlxBitmapTextField#draw(): use DrawStackItem#setDrawData()
FlxBitmapTextField: replace (get, set) properties by (default, set)
Added formatParse to FlxText: t.text="show $green text$ between dollar signs"; t.formatParse([greenFormat],["$"]);
formatParse now explicitly takes an input string
changed line to be less ambiguous
FlxText: added errors and checks to formatParse
FlxText: formatParse, updated usage example
Merge branch 'dev' of https://github.com/steverichey/flixel into dev
FlxText.formatParse: Now works with FormatMarkerPair, updated usage instructions
FlxText: changed formatParse to applyMarkup, FormatMarkerPair to FlxTextFormatMarkerPair
