removes quote from fns arg in view-server-fns macro

Allows fns argument to be passed by symbol, ie:

    (view-server-fns :javascript {:confirmed   {:map "function(doc) { emit(doc._id, doc); }"}}))

works now, but

    (def my-map {:confirmed   {:map "function(doc) { emit(doc._id, doc); }"}})
    (view-server-fns :javascript my-map)

does not. Unquoting should not be a problem since a map evaluates to itself.
