Tales Beyond eftir Trond A Ekseth

It currently requires digital dice to be enabled on DNDBeyond.

In addition it also does the following:
- Adds dice rolls to descriptions with support for replacing "your Dexterity modifier" with the proper value.
- Adds dice rolls to extra creatures in the character sheet
- Adds dice rolls to monster pages
- Hold alt/ctrl/shift while clicking the button to roll double dice for ADV/DIS rolls

Things temporarily not working due to changes on DNDBeyond:
- Adds off-hand attack to light weapons when character has Two-Weapon Fighting
- Fix the dice used on Chaos Bolt
- Adds separate rays for Magic Missile
- Adds a separate entry for damaged rolls with Toll the Dead
