`warnMixModes` temporarily disabled

Created by: benfry

The warnMixedModes section of the Processing.g4 grammar was breaking autocomplete.

(See https://github.com/processing/processing4/issues/491 for that issue)

The commit that caused the breakage is https://github.com/processing/processing4/commit/0f9b290398aac86ef56fe3c4e9c3ff88fdd53466

The temporary workaround is in https://github.com/processing/processing4/commit/caf1ba90b63d7c6fbcdfbe0586cf848cb353d1dc

This will affect 4.0 beta 9 unless we happen to get a fix before then.

@sampottinger This was a nasty one that I meant to ask you about…

Thanks for catching that @benfry. I should have some time tomorrow. I'll take a look!

Awesome, thanks!
