Changelog

0.8.0 (unreleased):
- Break: Removed the macros for GbaCell access in favor of just methods. I had at first thought that they'd assign registers and then inline, but it turns out that the inline phase happens way before the register assignment phase, so the macros were unnecessary (and clunky).
- Break: The IrqFn type is changed to pass the function an IrqBits instead of a bare u16.
- Adds functions to pick a screenblock location (one for each screenblock type).
- Add BitUnPack BIOS function.
- Add the CGA_8X8_THICK art data.
- Greatly improved documentation.
0.7.4: Adds mGBA logging support.
0.7.3: Fixes "multiple definition" errors with the AEABI division functions. Filed a PR to fix this soon: https://github.com/rust-lang/compiler-builtins/pull/495
0.7.2: First version that configures docs.rs properly!
