Further optimizations in Aimo-script terminology

- The objective is to further simplify the terminology and the help-text.

- In script, the keyboard power-operator ^ is automatically translated to the Aimola power-operator; this eliminates the need for its user-symbol toolbutton (users can manually remove it).

- Bitwise-xor (rarely used) requires the Aimola-operator (is more distinctive).

- Numeric comparison terms have changed from "about..." to "fEqual..." (fuzzy equal), with fEqual() as typical choice.

- If the Aimo is run directly via Aimo-menu, the new terminology is "Direct-run Aimo"; alternative terms have been removed.
