make urifind input/output streamable

This is a good idea, but the sort options can't go away.

Why was it necessary to remove the sort and reverse options?

Because those options require having all URIs in one array that can be sorted at the end. The streaming patch makes urifind print found URIs immediately, without accumulating them. I thought the sort options weren't essential because you can restore the old behavior using urifind | sort or urifind | sort -r, so I simply removed them instead of writing more complicated code that may or may not use @uris depending on the command line options used.

Ok, you've convinced me the features are redundant with sort and streaming is more important. As a sop to backwards compatibility, would you add error messages if -s or -r are used? Something like...

-s has been removed, consider "urifind | sort" instead.
-r has been removed, consider "urifind | sort -r" instead.
