Update javascript to find price when no levels are created. We do this by using a jQuery call instead of a javascript, in the event that nothing is found.

Also, if no price options are set, we assume that this is a pwyw/donation project, and set base price to 0.

Lastly, we only set variable pricing true on FES submit when a reward level w/ price is set.
