LBRYNet daemon

Adds a daemon for lbrynet. Currently commands are limited the following:

download_name(name)
resolve_name(name)
get_downloads
stop

This allows other programs to easily interact with lbrynet, such as
LBRYURIHandler. LBRYURIHandler can be built with py2app, the resulting
plist file must be edited in the same way the committed plist file has
been edited. When built and installed to the /Applications folder
lbry:// domain names will download and open the corresponding file so
long as the daemon is running.
