Small refactoring of proxy handling
support for upstream proxy
if behind a corporate web proxy, you must define a proxy (host, port,
user, password) via the option --http-proxy, as net/http doesn't read
the environment variable HTTP_PROXY
Refactor option parsing
Adds support for "dry run" mode.
No bookmarks are deleted in this mode - those that return 404
are just logged along with any other non-200 responses.
Adds support for HTTPS URIs.
Simplify and refactor
Delete outdated URLs too
Finally also delete ENOENT links
Fix #2 and update gemspec for next release
Add progressbar and logging
Switch from Delicious to Pinboard
Initial support for redirects
