Michael Sevakis 21e2b595c2 Prevent spurious recompiles on account of changed version.
After a local commit, any file that included version.h would have to
be recompiled on account of the changed version string. This changes
version.h in the build directory to rbversion.h and includes the
preprocessor macro from rbversion.h in firmware/common/version.c so
that only that one file needs to be recompiled after a local commit
rather than a whole slew of them.
