A bit tacky, but T-cycle accurate emulation of LYC write conflicts on the CGB. Only single speed mode verified. Closes #54

SDL2: Update to SDL_OpenAudioDevice()
...
Instead of the legacy SDL_OpenAudio() method, we now use the newer
SDL_OpenAudioDevice() functions. This fixes audio in Windows if the SDL
version is 2.0.6 or higher.
It also allows us to use 48kHz audio for Windows (96kHz somewhat works
too, but since we don't get absolutely smooth audio with it, I'd stick
with 48kHz for now until we find a solution. 44.1Khz is available as
fallback for SDL 2.0.5 and lower. Yes, the 2.0.5 to 2.0.6 transition was
quite harsh in terms of Windows audio support...

SDL2: Write battery file information before issueing RESET_COMMAND
...
Before performing the GB reset, we should perform a GB_save_battery.
Otherwise, resetting the emulation will kill ("kill" as in simply don't
write them into the .sav) all changes made to the battery save since
sameboy was started.

Fix savestates in SDL2 port
...
Because SDL_SCANCODE_0 comes *after* SDL_SCANCODE_9 in the SDL keycode
table, we have to check if the keycode is between >=1 and <=0. We also
have to substract SDL_SCANCODE_1 in order to set command_parameter
properly.
Errata: Currently, the savestate created with CTRL+0 is created, but
refuses to load on Windows (working fine on Linux).
