Fix #275 - removed unused files.

These are the last few files to remove from the code which are not used. If they need to be recovered, then you can run the following:

git checkout $(git rev-list -n 1 HEAD -- "<filename here>")^ -- "<filename here>"

Fix #332 which caused Q_rsqrt to produce NaNs.

Code was trying create a normal from a 0-sized normal. I've changed the
SP code to reflect how it looks in the MP code.
Fixed another problem with Q_rsqrt giving NaN.
Merge branch 'master' of github.com:xycaleth/OpenJK
Fixed crash on vjun1 in tie bomber cinematic

When the tie bomber cinematic is shown, the game might crash. This is due
to the bomb falling efx being attached to a model which doesn't exist (and
therefore is not loaded).
Fixed another case where Q_rsqrt gives NaN.
Removed unnecessary assertion.
Removed these debug messages from final build.
Add missing BOTH_KNEELATTACK to SP's animTable (enum2string)
Removed some references to non-existant effects in SP.
Parse wind primitive in SP fx code.  (Is not actually used in SP or MP, but MP at least handled it).
