Whitespace in class attribute causes selector trouble.

[brendo_]

See the attached testcase is probably the easiest way to understand this bug.

Pretty much, the $('.field-date') finds the correct elements, but then in the each loop, $(this).hasClass('.field-date') fails when there is extra whitespace between the classes.

I think there might be two bugs here, because the original $('.field-date') finds the correct elements regardless of whitespace, but then hasClass chokes on the whitespace.

A pure JS test is provided too, which shows the correct results (two raw:true's)
