Add a community_details feature for the community name and links

The community name, Discord, website, status, GitHub, and Patreon links
lived in exp_legacy/config/server_detail.lua, so changing them meant
editing the scenario. They are now the community_details feature and can
be edited from the Scenario Features page.

Chat auto reply, help bubbles, and the readme read the live config
instead of copying the values when the file loads, so an edit shows up
without a restart. Help bubbles store the location name in their task
and build the messages each cycle; the readme tab tooltip can be a
function which is called when the readme opens.

Every feature gets an enabled switch from the framework. There is no
sensible meaning for a disabled community name, so the values are
always used and the feature description says the switch does nothing.
