Make it able to highlight progress bar related acet-* functions

[Sen-real]

Objective

Support highlighting 3 more acet-* functions which are related to progress bar.

Abstractions

Add 3 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 CAD Forum:

• acet-ui-progress-init
• acet-ui-progress-safe
• acet-ui-progress-done

Tests performed

Both highlighting and auto-completion work as expected.
