Make Lord of Thunder more convenient for DM

[InnilToo]

When you hit with an attack, you can choose to expend one of these charges to do one of the following:

• The target must make a Constitution saving throw against your warlock spell DC. On a failed save, they are stunned until the end of their next turn.
• The target must make a Strength saving throw against your warlock spell DC. On a failed save, they are pushed 15 feet away from you in a straight line.
• If the target is further than 5 feet away, they must make a Strength saving throw against your warlock spell DC. On a failed save, they are pulled 15 towards you.

• The target must make a Dexterity saving throw against your warlock spell DC. On a failed save, they are knocked prone. The target is deafened and cannot take reactions until the start of their next turn.

  There us a variety of uses and different saving throws. Foundry only supports one saving throw per feature though.

• Ability to add more than one saving throw button added in newest update of Roll Groups. However we could still create something that shows only 1 variable button.
• The 'stunned' condition could be added to the item to be transferred via ET. Same with 'deafened'.

As for pushing and pulling, I am considering some implementation of this, but not sure yet. Depends if The Player would even want to be able to do this from their end.
