Now you can run your workers through a SOCKS proxy with the -S flag!
Authentication at the command-line through fully-qualified URLs as well
as interactive authentication are now supported.
I may revert the try/except block in LinodeProxy's constructor should it
be found to be non-advantageous in further testing. Performance in
creating large quantities of Linode proxies is still dog slow, may use
concurrent.futures to speed this up in the future (hah) -- this will
require a major rework of the downloader main().
