[PATCH 1/2] url-lib: don't add existing handlers multiple times

[Will Woods]

Every time url-lib gets imported we end up making the list of handlers
longer with redundant entries. That's silly - we shouldn't add items
that already exist.

Note that this means you'll have to manipulate the handler list yourself
if you want to change the position/priority of existing handlers.
