clousure compiler warnings

[Ognian]

I'm using my new grunt knowledge to squeeze jsonary thru googles closure compiler.
Although everything looks good and the resulting jsonary works good, I'm getting 4 warnings which I think are worth to look into:

Thanks, I'll have a look at these - some of them do indeed look suspicious.
