Compress the js with uglify js when running the rake task
Fix a bug where extend does not return an Object.

'extend', when compiled to js, was returning an array of
arrays rather than an object due to implicit return.

This broke the options sent to setCookie, because the 'expires'
attribute of the returned options object was always undefined,
so the cookie expiration field was never set as
options.expires.toGMTString().

As a result, the abbaVariant and abbaPersistComplete cookies
incorrectly had no expiration date or a received a default expiration
from the browser, rather than the 600 day expiration specified
in the code.
Support an "expires" option for setting # of days it will take for
Abba cookies to expire.
Fix bug where defaults weren't actually being used.

@defaults was always undefined due to scoping issues, so defaults were
never actually used.
