Computronics 0.4.2 for 1.7.2

-The ability to control the volume of tapes has been temporarily
disabled, due to netcode changes in 1.7.2 causing violent crashes with
the volume byte added to the audio packets. This will be revisited in
the near future.
-New version of Nether Star Tape added: crafted with 4 Nether Stars and
one tape track, it is capable of holding 128 minutes of audio, or enough
data to properly accommodate a FAT16 partition.
-KNOWN BUG: Tape Drive GUI is nonfunctional, and has been broken since
0.3.0. Will be fixing in a later release.
