SDL: Remove side effect of setlocale() call to get Language.

This is to fix bug #3615148 -  "ALL: sscanf("%f"), atof() etc. not
portable due to Locale"

The side effect of setlocale("") is to change the active locale
from the default of "C" to the detected system locale, but this
changes the behaviour of sscanf() and several other functions
in a system dependent and non-portable way. This has caused
bugs in the ZVISION engine when running Zork Nemesis.

The solution is to restore the default "C" locale after the call
to get the language.

Thanks to criezy for working out this fix.

SDL: Fix invalid memory access in getSystemLanguage.

A call to setlocale can invalidate the string a previous setlocale call
returned. Instead of saving a pointer we copy the returned string now. This,
for example, fixes invalid memory access on my system.

See de8da01b0e8a309b9ed3f5b0f152ebbcf8f4af37 for the commit introducing the
invalid memory access.
MADE: Create MusicPlayer in run() instead of MadeEngine's constructor.

This fixes MT-32 emulator initialization. When the constructor is run the
paths like extrapath etc. are not yet set up. Thus, the MT-32 emulator would
not be able to find the necessary roms in case they are in the extrapath.
AUDIO: Do not add extrapath to SearchMan in MT-32 emu code.

At the point where the emulator is created extrapath should already been
added to extrapath. If not, the check in checkDevice already failed and thus
adding it would be too late anyway.

It seems this was added in 805b21181ab7138da6960ade703b25716120fc29. The
comment about it being a HACK has been removed in bbad3f333a9227ccb1de633a0fe92d9e01ad7bb3
but it's not clear to my why... At any rate, this should not be here.
