rsmaz 0.0.4

Short String Compression for Ruby. RSmaz is a pure-Ruby port of the Smaz short string compression algorithm by Salvatore Sanfilippo and released as a C library at: http://github.com/antirez/smaz/tree/master I've done some initial cleanup of a pure Ruby->C port, but this is not yet complete. It does pass the specs, however! Feel free to clean it up as it's a bit memory inefficient right now... :)
