Bug fixes

Fixed bugs in syntax and other things.
Updated link_message prelude for consistency

Made some minor changes to make link_message events start the
same way. Made a few substantial changes to achieve the same
result. Made some buttons disappear when RLV not active - because
they make no sense at that time.
converted pleasureDoll to allowStrip

The "pleasureDoll" is not a Doll (type) at all but an allowed
feature; change the name and add a definition to match.
Make collapse() re-executable

Should be able to run collapse() several times with the same
setting and no adverse effects.
