Stopping a source in the middle of playback can causing undesirable "popping"
from a sudden change in amplitude. Setting the source gain to 0 gives OpenAL
the opportunity to ramp the source's output to 0, where it can be safely
stopped without causing a sudden change in amplitude.
This isn't supported with the OpenAL backend, and instead of trying to make a
workaround for it, a better approach would probably be to make a FileReader
implementation that handles URLs.

- added arrays to the config to hold entries for the softsynths' config files. This is not active yet, but will later be used to give the user a list of config options instead of having to type it by hand.
The needed headers are now included in the repo, which for these libraries is possible thanks to a stable ABI (at least on Windows, the other platforms still need to be checked but the headers only add, never remove or change existing content.)
The big advantage of this setup is that it allows building the project on Windows without any necessary setup - all that needs to be provided is the DLLs from the binary package.
This still requires some fixes for macOS and Linux. On MacOS the proper library names are missing and the ones for Linux are not verified. Both platforms should work, though, if the dynamic loading is disabled.

This is somewhat brute-force thanks to the surprising lack of good documentation for the Ogg headers. The only other option would have been some rather bloated library for a function that should be 25-30 lines at most.
The idea is to have more control on the game side instead of dealing with these formats in the backend, which was done for FMod because it already had the decoders implemented.
However, with OpenAL this setup makes no sense and only complicates future extensions that can be better handled at a higher level.
(Is there anyway to tone down GCC's warning level? It outputs too many false positives for potentially uninitialized variables in which the genuine errors get drowned.)
- enable precompiled headers for all non-system-specific MIDI devices.
- moved the native Windows and Mac MIDI devices into their respective sections in the project file so that they won't get compiled on the other ones.
This one was particularly nasty because Windows also defines a DWORD, but in Windows it is an unsigned long, not an unsigned int so changing types caused type conflicts and not all could be removed.
Those referring to the Windows type have to be kept, fortunately they are mostly in the Win32 directory, with a handful of exceptions elsewhere.
A major part of this device's implementation details about how to handle the callback were not encapsulated by the device class at all, they were #ifdef'd into the streamer class.
This puts everything into the device class which now exposes a clean interface to the rest of the game with no special handling aside from calling two additional virtual functions that are empty for the other devices
* make the critical section local to the respective platform instead of polluting everything with system specific symbols.
* moved system specific class declarations into the source file instead of having them in the global header.
This commit temporarily disables the Windows system device because it cannot be done without polluting the global header and still needs a bit of refactoring.
