Finished rescan functionality amongst other things

Wrote rescan function

Implemented -v,--verbose switch for rescan

Added -v,--verbose to help text

Reformated help text to fit an 80 column display like real man pages (probably
have to redo this one more efficiently later)

Moved echo open on socket_test to after closing the file handle

Moved printing of host:port protocol out of socket_test since it should only
return a "boolean-ish" value
Updated README file

It should be near-complete now.
