Some configure stuff done. All aint 100% yet, but good enough.
Keep config.h.in in the repo so autoheader isn't compulsory to run.
Added check for inttypes.h in configure.ac.
Removed files that need not be CV'd.
Woot! This is the clean up of the importer object.
Clean up the context before Pike_error is thrown.
Added some info methods about libsass version.
Improved configure.in to check for features in libsass.
