Add /SCFM and /SCMPU options, to select which cards to use for FM/MPU

[jiyunomegami]

It will print which card is being used, like this:
OPL3 hardware(2:ALS4000) at port 388: enabled.
MPU-401 UART hardware(1:YMF) at address 330: enabled.
SB Pro(3:TRIDENT) emulation at address 220, IRQ 7, DMA 1: enabled.

*ALS4000 and Trident drivers are not included in this.

The /MCOM option default is now 9: hardware only (no serial output)
Other changes:
[Allow IRQ 9 with /I option] (I have a motherboard that can reserve IRQ numbers only from 9 on up)
[Base 10 option support] (Used for /SC* options and /K option)
[Allow arbitrary sample rate between 4KHz and 192KHz with the /K option] (Good for testing)

Also, like I mentioned in #84 I removed -O2 and -save-temps from CFLAGS/LDFLAGS

OK, I was just about to ask the base 10 one,
You can utilize the CMD flags to add a base 10 bit, by default it be hex, with that bit it be decimal.

Or I can change that part later after merging.
I just got some time and please wait before I merge it.

The base 10 stuff, you can just change it later.
I fixed the display of current settings/changed settings too.
So if you haven't done that, you can just update opt_base to use the base 10 bit.

As you last mentioned Trident card driver are not included, so there might be linking errors. but We can fix later if that is the case.

I made a mistake when merging, putting back EMU20KX_sndcard_info. EMU20KX will be replaced by CTXFI.
It is OK for now because AU_CARDS_LINK_CTXFI etc. are not defined yet.
