FMSLogo Code

Clarify the instruction in the <replaceable> part of the example for SETACTIVEAREA.

Fix a few grammatical errors

Translate the front-matter for the chapter on Networking Commands to Spanish.
This translation was based on Rosario Ruiz's translation of the MSWLogo manual.

Fix a few adjective/noun gender+count disagreement mistakes.

Fix a bad translation of "such that".
It replaces "tal que" with "de modo/manera que" or completely rewrites the sentence.

Translate the documentation for the bitmap procedures into Spanish.
This translation is based on Rosario Ruiz's translation of the MSWLogo manual.

Add a missing period to the end of a sentence.

Initialize a NODE** to NULL instead of NIL.
NIL is a typed NODE* that means "empty list" has no meaning for any other pointer.
NULL means "not yet set".

Fix bug #497; (1 2) no longer crashes FMSLogo.
The problem was that parenthesizing/treeifying the expression
failed, since 1 is not a procedure and therefore FMSLogo doesn't
know how many parameters it should take. The "tree" of 1 was
then dereferenced to get the "car" field, which crashed.

The fix, which copied from UCBLogo, is to use the tree as-is
if it's not a list (that is, don't dereference it). This results
in a "i don't know what how to 1" error, which I think is the
correct error for such an expression.

Remove contradictory information.
The documentation had previously stated that BURIED output all *unburied* items.
