Switchy Proxy

Changes:

• Alias commands to /switchy module config switchy_proxies:proxies.
• Rearrange the add/remove and preset arguments to allow for non-preset commands (sorry about the muscle memory!)
• Add the latch command to toggle latch mode, where proxying will change messages until disconnect or another proxy.
  • Not sure if this should get cleared when an actual switch happens, too, so we haven't done that yet.
