Stepping out of a function which was called as a new thread now breaks at the line which was interrupted, instead

Fixed load-time errors sent to stdout showing incorrect file/line number in some cases.

Fixed detection of invalid suffix on a hotkey, such as Hotkey "a pu".

Fixed #Include to correctly "close" any built-in variable it reads (no known impact on real-world scripts).

Fixed Until preventing subfolder recursion in file loops.

Fixed DllCall to throw when arg type is UStr.

Fixed icon loader to prefer higher bit-depth when multiple bitmaps of the same size are present.

Fixed SendInput failing to release LCtrl if it had already released RAlt and the layout does not have AltGr.
