Call button hit script issues

[JennaMalkin]

With #91 , I added a call button hit script, but it may have some issues.

It has an INST at the beginning which shouldn't be there, and may cause issues with the script.

Secondly, it uses a WAIT of 7, which, while recommended in the Meerk Toy tutorial, may cause issues with being interrupted.

Thirdly, for future development, it should include a 'DOIF FROM EQ CREA' check around the stimulus, for future-proofing in case we want to add more chemicals manually, which is creature-specific, or allow critters to hit buttons, etc.

Some of these issues may be fixed by #98.

@NeoDement reports that the lift button can occasionally get stuck on the wrong frame when hit.
