Log:
Clarify Derek's code to be licensed "GPL v2 or later" as he has confirmed in private email.

All of his other code has been licensed this way all along anyway.

After this change, all source code files are licensed under both
GPL version 2 and GPL version 3, which gives us enough flexibility in case any
requirements might switch to GPL v3-only. But currently we are for sure both.
