Support highlighting 2 more acet-* functions

Objective

Support highlighting 2 more acet-* functions

Abstractions

Add 2 more acet-* functions into data files for highlighting and auto-completion. This is to address a part of #221.
They are not documented in acetutil.chm, but explained on https://www.afralisp.net/archive/lisp/acet-utils.htm:

• acet-error-init
• acet-error-restore

Tests performed

Highlighting and auto-completion work well with them.
