m!m's fix for Mantis #3131: contrary to the xt change from r11138, NULL is only returned on vm_malloc failure (so should never happen in normal execution)

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11179 387891d4-d844-0410-90c0-e4c51a9137d3
improve sexp code for obtaining pitch/bank/heading with the following changes: 1) use an alternate algorithm for extracting angles from an orientation matrix 2) properly round floats to integers when converting to degrees

remove the Error (originally Assert) from r1675 and add back the comment removed in r8005

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11181 387891d4-d844-0410-90c0-e4c51a9137d3
minor reorganization

added a sexp to pause and unpause music that is currently playing

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11183 387891d4-d844-0410-90c0-e4c51a9137d3
it's good to check whether the music is paused, for bulletproof-ness

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11184 387891d4-d844-0410-90c0-e4c51a9137d3
when the game returns from a paused state, don't unpause the music paused by sexp

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11185 387891d4-d844-0410-90c0-e4c51a9137d3
this should fix Mantis #2888 (allow for head.ani files without letter suffixes)

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11186 387891d4-d844-0410-90c0-e4c51a9137d3
a more future-proof way to keep track of explicitly paused audio

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11187 387891d4-d844-0410-90c0-e4c51a9137d3
move this around for more logical flow

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11188 387891d4-d844-0410-90c0-e4c51a9137d3
Fix mantis #3133. Fixes logic errors in factor_table not being sure if it's supposed to be 0-based or 1-based at different times.

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11189 387891d4-d844-0410-90c0-e4c51a9137d3
fix Mantis #3135: account for the case when the game is paused before being minimized

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11190 387891d4-d844-0410-90c0-e4c51a9137d3
Correct copy-paste error in check_sexp_syntax() from the armor types commit.

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11191 387891d4-d844-0410-90c0-e4c51a9137d3
Related to r11189: avoid calling factor_table::getNextSlots() if the ship doesn't have the dynamic linking flag.

Basically, hitting "o" on any ship with more than 6 slots in a bank could crash FSO, even without the flag. Reported by Spoon.

fix Mantis #3132 (is-iff returns true when the target is destroyed)

git-svn-id: svn://svn.icculus.org/fs2open/trunk/fs2_open@11193 387891d4-d844-0410-90c0-e4c51a9137d3
