Python "PEP-8"-style Formatting for Formula Tool

[ejhaley]

It would be fantastic if there was auto-formatting for the Formula Tool (and even other tools, possibly).  The auto-formatting would function similar to Python PEP-8 style, either 4 spaces or an indent on each new line.  This could also be expanded to modify the existing autocomplete functionality of an IF statement with appropriate formatting.

Auto-Complete Current State Example:

IF c THEN t ELSE f ENDIF

Proposed Example:

IF c

    THEN t

    ELSE f

ENDIF

This would dramatically increase readability for lengthy nested IF statements or other complicated functions within the Formula tool.  It would also save a tremendous amount of time when we have to go back and format those functions later.
