Haxe 3 - Replace flash.Vector with haxe.ds.Vector

Replace constant sized Vectors with new haxe.ds.Vector
Enable RLE (run length encoder) for all targets

Changed RLE to use haxe.io.Input/Bytes instead of flash.ByteArray
replace Root class with de.polygonal.core.log.LogSystem
(use LogSystem.config object and call LogSystem.init() instead of Root.initLog())
use Arial in TextFieldHandler
fix LogHandler.setFormat(), add LogHandler.getFormat()
simplify Log class
workaround for cpp/android/ios warning:
this decimal constant is unsigned only in ISO C90
use haxe.ds.Vector in Observable
haxe3 fix
goodbye haxe2.x
move resource loader to flash lib
