Bits and Bobs - TGZ Library

I'm not entirely settled with any database format, as the old one is restrictive and ridiculously wasteful, and the new one relies on an external executable doing all the heavy lifting. For this reason, I thought I'd have a go at writing some code that would allow me to support .tar archives and .gz files, so that in combination, I could have my database saved into a .tar.gz format, relying on no external compressor or decompressor to do anything, meaning my executable can be distributed entirely on its own. Yay!
