The great github migration

I've just migrated most of my projects from the sinking ship that is Google Code, but the wikis and readme.md files aren't setup yet:

https://github.com/richgel999/rg-etc1
https://github.com/richgel999/fxdis-d3d1x
https://github.com/richgel999/crunch
https://github.com/richgel999/picojpeg
https://github.com/richgel999/imageresampler
https://github.com/richgel999/miniz
https://github.com/richgel999/jpeg-compressor

The wiki data was auto-migrated into the "wiki" branch.

I haven't migrated LZHAM alpha (used by Planetside 2) yet. Still deciding if I should just archive it somewhere instead because it's a dead branch (LZHAM now lives here, and the much faster compressing development branch is here).
