Subject: [PATCH 03/24] Revert "MF2_PUSHED is now MFE_PUSHED, for the simple
 reason that it makes more sense as an eflags object flag than a flags2 object
 flag!"

Subject: [PATCH 04/24] Readded EvalMath to Lua.

There is a caveat to this: The first time EvalMath is used, a
deprecated function warning will be shown to the user that tells
them to use _G[] instead.

This reverts commit 9d36cf37bd6fc1e5e0e9770031925db3a92a9929.
