A buffer looks like an object in js

[arj03]

You can't current use verify if the signature is a buffer. This fixes that problem :)

If the signature is a base 64 string, is the isObject the right validation here?

[arj03]

@davegomez the idea is that if you are passing in an object instead of a string, you should rather use verifyObj. This function works with both string and buffer. It's just that in javascript typeof (buffer) == 'object' ;-)

@arj03 A little test would be nice, but obviously this is mergeable because it just improves the codebase.
