Release v0.2.3

Again: If you are using custom width/height and/or offset values, do not overwrite the config.xml, but rather make a backup and copy them over.

*Fixed deck in overlay not being sorted before games
*Tracker no longer reiterates though complete log when switching decks (means no more lag when switching decks)
*Number of cards in deck when editing/making new now displayed again
*Checking/unchecking highlight cards in hand updates correctly again
*Burnt cards by opponent now detected

*Maybe less issues with overlay disappearing (?)

+Added options to move decks in overlay
+Added option to set overlay opacity
