Removed MANIFEST, which is a setup.py output.

It should never have been committed in the first place.

Not sure I appreciate why it's not emitted into dist/ by setup.py, though.
Added a .gitignore.

This always happens, at some point. Here's that point, for this project.
Started on a C reference implementation to test against.

Downloads the C source for the core LZJB compression/decompression from GitHub, to avoid re-distributing them.
Changed format of the prepended size to actually make sense.

It's simply a variable-length little-endian integer, encoded using 7 bits per byte, with bit 7 set in the final byte.
Added size-handling, and implemented decompression.
Re-structured the driver code, to support -c and -x modes.
Made compress() require its input to be a bytearray().

Removed built-in code that attempted a conversion, felt pointless and silly.
Dropped version to 0.1, since that's more like it. :/
