Blank white screen (WSOD) on javascript load after node view with blank variable dropcap_selectors

When you first enable this module and view a node, the node shows up and resolves to a WSOD. That's probably frightening off the noobs, for sure.

Turns out that if you add jquery on the admin screen, wsod goes away.

Simple enough, just check to see if dropcap_selectors is empty before loading javascript.

A half a line of PHP. See attached patch.

Thanks for a fun module!
