v0.11.1-rc2

ZetaBot v0.11.1-rc2

A small update with enhancements to bot behaviour, as well
as quality-of-life improvements for path authors.

Here's what's new since v0.11.0:

• Bots can now activate cross lines (W1 and WR)!

• Pathnodes created will begin at the player,
  instead of in front of.

• Some internal refactoring for the way pathnode
  types are plopped.
