Add a no push option & solve difficulty > skill issue

[ulrikL]

Add two new versions of rolling dice that does not allow pushing the die roll.

!myz-np and !wmyz-np

[ulrikL]

Add a difficulty dice inline roll part of the script. If the scripts are called with a following solution it handles the difficulty dice correctly.
"!myz [[(?{skill}-?{diff})d6]] [[1d6]] [[1d6]] [[(?{diff}-?{skill})d6]]"
Since the difficulty dice are last they can be ignored and can be considered optional.

@shdwjk Are these good enough or do you want them done in a different way?

• On your line 122, should probably retain the html entity for ampersand.

• Take out lines 683-692 and instead add a second case for whisper (this is just another label to the same whisper code):

      case '!wmyz':
      case '!wmyz-np':

a second case for non-whisper and code to determine nopush (this is just another label to the same non-whisper code):

      case '!myz':
      case '!myz-np':
          nopush=/-np$/.test(cmd);

Since the switch statement falls through, this will use the existing logic to determine whisper and then additionally check both commands for the trailing -np indicating a no push roll.

• You took out the case for -6 on line ~759 for skillDiceArray. I don't recall why it was in there but just want to make sure it was intentional.

Other than that, it looks pretty good! I don't know the mechanics for difficulty, but I'll trust you do. =D
