Highlight: Configure incoming highlight output

Added configurable option $stripIncomingHighlights which expects either $true, $false or $ok
 $true: Strip incoming highlights
 $false: Don't script them, and apply $c1 on it, also make your own name stand out.
 $ok: Show them exactly as they are (persevere)

Add "/trigger_highlight [optional: anything]" to test your highlight, add any input to it to add colours to it
