PATCH: GlobalAddAtomA check for invalid ptr

[Marcus Meissner]

Hi,

This checks the string passed to GlobalAddAtomA() for being a valid pointer.

The Ikea kitchen planner passed 0xcccccccc for some reason and works much better
after this patch.

Ciao, Marcus

Changelog:
	Check the passed string to GlobalAddAtomA.
