* Frees cpAudio pointer in VOICEREC_deinit()
* Validates that the ship/wing can actually take orders, and validates that it can take the specific order in question before trying to send it.
* Reports the confidence of the voice match if DEBUG_ON is set.
* Various commenting changes based on the patch.
Not included: using confidence to discard voice matches that fall below a certain confidence level. I haven't noticed a tendency towards spurious matches, and I didn't want to introduce this without additional data, especially when it might cause problems for people with different accents (and ESPECIALLY without a setting to tweak the threshold value, which the original patch did not have; it was hardcoded at 90%).
Should result in reduced BMPMAN slot usage with certain scripts as bm_unload() unloads the image data but holds on to the slot, while bm_release() releases the slot.
As headani's (both ANI & EFF) are streamed there's no need to have
the anim data in bmpman, the streaming code does that with only two
slots, rather than one slot per ani frame
Also fix a "leak" in the streaming code use of bmpman slots. i.e. each
time a message was played another slot would be used & not released
In 9ec10dd I thought I was fixing a memory leak, but the actual scenario was that the freeing was just delayed until later. This removes the freeing added by 9ec10dd and changes the free() calls into vm_free() calls.
While investigating issue #345, it was discovered that `popup()` is getting called during `gr_init()` (and since this is before `gamesnd_parse_soundstbl()` gets called, the eventual call to `gamesnd_play_iface()` results in reading invalid memory). Given that this is basically relying on a feature in the middle of the function initializing it, and given that both lines are preceded by `mprintf()` calls saying basically the same thing, it seems the best solution is to just remove the troublesome lines altogether.
Makes save_mission_file() and autosave_mission_file() delegate to a new save_mission_internal() function. Tested and works with both manual and automatic saves.
As an aside, this fixes a slight inconsistency between manual and automatic saving (which inspired this refactor in the first place): when the order of save_fiction() and save_cutscenes() was swapped (in r10886 a.k.a. d6e0a73), autosave_mission_file() wasn't also changed, so autosaves of missions with "#Cutscenes" sections can't actually be loaded.
