Move all theme files to root, remove theme.

NOTES:
- Since this theme is handrolled and it's unique to me, having a separate git repo for it doesn't make a lot of sense.
- Used git mv to move all files and assets
- Removed all bower dependencies because I also don't use bower
Removed theme directory
Update to documentation.

Notes:

- Moved CHANGELOG
- Removed a lot of cruft from README that really belongs in a new blog post instead
Removes CHANGELOG.md
