Fix Bug #599; The output list of macros that are run as input to a procedure and which define local variables are now evaluated in the caller's context, not the context of the macro.

Add regression tests for NAME, including a regression test for Bug #598.

Mitigate Bug #598.
The definition of QUEUE and DEQUEUE were copied from UCBLogo to make it less likely to have a conflict with variables names in the caller's context.
This is not a fix, because the bug still exists.
However, this is still an improvement, as it makes FMSLogo and UCBLogo have the same bug, so code that works in one won't fail in the other.

Standardize on "scale of the screen window" instead of "zoom factor".
Both terms were used interchangably, and it's better to have a single term for each concept.
I preferred "scale of the screen window" because it's what the first sentence of ZOOM said it was changing.
It's also more precise than "zoom factor", which doesn't mention the screen.

Implement Feature Request #143; MACHINE now outputs the current screen window scale as the 18th item in the list.

Fix a broken header guard (thanks gcc for pointing it out!)

Add a "See Also" to KEYBOARD to link it to SETFOCUS and GETFOCUS.
Also, explicitly document that SETFOCUS "FMSLogo will give focus to screen window, not the commander.
These changes were requested by Manfred Zindel on Support Request #66 after he spent a day or so not understanding why KEYBOARDON wasn't working.
