Custom error message doesn't get formatted if flavor==CALLABLE

[M3t0r]

Schema(lambda i: i == 5, error="Formatstring: {}").validate(12)

produces an exception with the message "Formatstring: {}" and not "Formatstring: 12"

I had to change line 309 to

raise SchemaError('%s(%r) should evaluate to True' % (f, data), e.format(data))

to get it working as intended.

You're also missing the documentation for this feature all together. Took me a while to figure out. And #4 is still open, too.

This is still a problem today! I'll send a PR...
