Removed whitespace between version and local level.

Version and LOCAL_LEVEL should not have whitespace in
between.
New Defines: __VERSION_COMMITID__, __VERSION_LOCAL__

Commit ID and LOCAL_LEVEL are now exported to LPC.
pragma rtt_checks implicitly defines save_types.

rtt_checks does not work without save_types, so they
anyway have to come together.
(the alternative: warn if rtt_checks but no save_types
 is not really better.)
