v0.2.2

Subo Beta-2.2 brings several bug fixes and new features.

Features:

• Subo now automatically checks for updates and notifies you if one is available (big thank you to @denopink for this!)
• Subo's proxy port (when running subo compute deploy) can now be configured with the --proxy-port flag

Fixes:

• Fixed a bug where Subo would crash when building a single Runnable with the --docker flag (#102)
