New Features

• CLI overhaul! New colors, help pages, and command structure. Most notably, rip -u <url> is now rip url <url>.
• Themes, which can be set in the config file. Right now, we just have them for progress bars, but expect much more to be customizable!
• Update checking is now done in the background, which will improve startup times
• Paid Deezer accounts are now supported, along with the old Deezloader server. I had to do this because of the recent unreliability of the server (#124 #119). To request items from the Deezloader server, pass --source deezloader into the command
• Concurrent downloads are now enabled by default, with max_connections set to 3.

Internal Changes

• The CLI manager has been moved from click to cleo
• Everything is now documented
