changeset 1330 ab94316bb52b
parent 1231 17badaf66ce4
child 1406 f5c07ec3c052
permissions -rw-r--r--
Updated license headers on virtually all files with extremely minor changes in the name of some sort of strange consistency.
All plugin and include file headers also have been changed to say about GPL3 instead of GPL2.
