Added x192a3u config file
Manually added processed config.h through cmds.sh. Modded Makefile to NOT run config.h.mk, the offending script.
Modded Makefile for correct MCU and toolchain path
Deleted cmds.sh. Reenabled config.h.mk, it will not run into infinite loop since we have added SHELL:= /bin/bash to top of Makefile. SH shell causes problems with config.h.mk. Also, we need to define MCU only in conf file.
No need to track config.h and config.mk as they are auto-generated
Fixed assignment of SHELL to /bin/bash in makefile. Improved error checking to make sure user runs make <conf_file> before trying make all. Changed xmega192a3u to xmega192a3 since avr-gcc doesn't support a3u yet, but they are more or less the same.
Updated gitignore to ignore autogenerated config.h and config.mk
