What's New:
* Fixed crash when trying to load invalid skins.
* Added IDENT function. This returns the app's version number as a negative integer, in -aabbccdd format, with 1.2.3f formatted as -1020306, for example. The number is negative in order to distinguish Plus42 from Free42, which returns positive numbers from IDENT.
* XROMs are now decoded immediately when pasting.
* Switched ^ and ↑ in the character set. The change is transparent to the user, but it restores code compatibility with the encoding of ↑ in Free42.
