Altered minified JS to avoid Tumblr hosting bug

If a user copy-pastes the entire HTML of a compiled game into a Tumblr

interpreted as Tumblr template variables, and stripped from the rendered
page. To counteract this, line breaks are inserted into minified code
before } symbols in potentially offending structures.
