re-disable changing resolution at runtime

FSO doesn't properly resize framebuffers or anything when the resolution changes, or scale to
different window sizes properly when resolutions differ, so although this code works it must be
disabled.

Having this ability disabled has also been recommended due to scripts not being able to deal with
resolution changes.
