bumped version for release

added tos programs that are used to interface to BaS_gcc from TOS. These programs are currently not build by default (need to call make in their respective directory for now). They expect to find a libcmini copy on the same directory level than you have your BaS_gcc folder.
Add format specifier to fix debug messages format
