Update version number in README

The README mentions the 0.4 release has been submitted for review, this
is outdated, it has been accepted and is now the version you can
download from the Firefox add-ons site.
Remove unused files

The `doc`, `locale` and `test` directories only contain placeholder
files, this makes it harder for a new maintainer to understand the
structure of the project so I simply removed them. Removed the
`package.json.backup` as well, it's a git repository, no need to keep
`.backup` files.

Conflicts:
	test/test-main.js

Keeping the test files for the main module
Whitespace

Remove trailing whitespace
Replace all tabs with spaces for consistency

Conflicts:
	data/popup.js
	lib/main.js

Large differences in the main file but the popup was a simple port change.
