Open username-removed-1357377 requested to merge change/switchRamparts into dev

Open friendly ramparts when a creep is travelling (action.travelling only currently) Creep calls out for them to be opened, and if the ally is running this version, they will open for the creep and close behind it.

The CPU cost of checking is actually quite low ~ 0.2 - 0.6 / room that gets activated, negligible for others.
