#89 Improve handling of space-before-colon headers

If a message comes in with a signature containing:

h=...:Date:...

...and a header containing:

Date : ...

...then that Date header is not replayed into canonicalization. Internally the header is stored exactly as-is and thus a direct string comparison match will fail when searching for headers to canonicalize.

Although DKIM is predicated on the message being properly formed, this is a case consensus feels should be handled by the implementation.
