AGK Core fixes

Fixed array FromJSON() crashing when converting an empty string into an integer or float
Fixed a problem with the print command not dealing with more than 20 digits in a float. Previously anything greater than this would cause a silent crash
Fixed a crash when using SetMusicLoopTimesOGG
Added a new find feature for unsorted arrays called IndexOf. An example of it use would be: index = array.IndexOf ( 123 ) – so index will be assigned the index of the array if it can find the value 123, otherwise it will be -1
SetEditBoxTextSize command reference updated
Updated command reference for Len and ByteLen
Additional information added to the tips section of the documentation explaining about case sensitivity and tier 1 apps and their bytecode.
