Tweak JS style and the relevant JSHint and JSCS checks.
Comply to the new style.
Remove `laxbreak`.
Remove `boss`.
Enable `requireCurlyBraces`.
Enable `es3`.
Switch to using plain `if/else` statements when there's no assignment.

The minizer outputs the same code anyway, and this has better readability.
Minor whitespace changes.
Switch to `(function){..})()`.
Run `grunt dist`.
More updates to the JSHint options.
Run `grunt`.
