Fixed loading of JPG/GIF files which are already open for reading.
Fixed misidentification of digits/xdigits by if-var-is.
Added a safety check for ControlGet Selected in case it is used with a non-Edit control.
Fixed variables being set to NULL in certain rare cases, causing crashes. The only confirmed case being when a string longer than 63 characters is returned from a function and assigned to a variable while AutoHotkey is running as a Windows store app.
Fixed InputHook callbacks failing after input is stopped and restarted.
