With this patch, entities can serve as a sound source whose position
updates relative to the listener. This implements the last missing
feature of my previous positional audio patch, which is moving sound sources.
Previously, all sounds were relative to the listener with the listener
centered at (0, 0, 0), and once a sound started playing, the position could
not be changed. Volume was set as an estimation of the distance to the listener.
These restrictions are now gone; OpenAL will handle the volume & panning
based on the distance.
The remaining problem is that stereo sounds are not attenuated, at all.
Lua additions:
- playSfx() takes an additional parameter now.
- entity_setStopSoundsOnDeath()
The first one caused the music to stop randomly on scene changes,
reproducible by changing maps with different music while holding 'G'
button to speed up time.
For some reason this caused the music to stop playing during the crossfade.
Wasn't able to find the root cause, so I added a little hack to kick the
music back on track if it stops unexpectedly.
The second one was a simple string case issue; mostly noticable because of
map background sounds not playing in loop mode.
(this is possibly a regression from an earlier patch, not sure)
- HTTP networking support, mods can be downloaded via the builtin downloader.
All network activity runs in a seperate thread, which is started
as soon as any network activity is requested.
- The master server is hard-coded to fg.wzff.de/aqmods/ if not specified otherwise;
this setting can be overridden in the config file.
- The mod selector screen is now a grid-view for much better navigation;
also works with joystick.
- VFS code is functionally similar to the old molebox-packed release
for win32. The game could also have its data shipped in a Zip file
or any other kind of archive.
- It is still possible to build without VFS support, but then the mod
downloader and soft-patching will not be available.

The most important commit messages follow:
[...]
This replaces all std::ifstream with InStream, and fopen(), ... with vfopen(), ...
Some code is #ifdef'd for better performance and less memory-copying.
VFILE is defined to whatever type of file is in use:
- FILE if BBGE_BUILD_VFS is not defined
- tttvfs::VFSFile if it is.
Other changes:
- [un]packFile() is now unused and obsolete. That code has not been adjusted to use VFILE.
- glpng can now load from a memory buffer.
- TinyXML uses the VFS for reading operations now.
- The rather clunky binary stream loading of glfont2 got replaced with ByteBuffer,
which gets its data in one block (necessary to use the VFS without implementing
a somewhat STL-compliant std::ifstream replacement.)
-------------
Implement loading mods from zip files.
-------------
Implement soft-patching game data files. (Replacing textures/audio/... on the fly)
-------------
Misc bits:
- Extended GUI focus handling a bit
- Fixed weirdness in texture loading... not sure but this seems more correct to me.
Actually, considering that the texture will have its native size after restarting the game,
the lines removed with this commit seem pretty useless.
The latter one caused sounds in mods not being properly cached (and not
played), if the internal mod path started with "./", which is the case
on windows since an earlier commit.
Apparently this was half implemented but not fully finished.
Mono samples work fine, for stereo, L/R panning does not work (due to OpenAL's limitation)
Also fixed: entity sounds should not play if a cutscene is currently skipped.
