Legacy Sheet Compatibility and Bugfixes

[TMGilchrist]

Hi Handyfon, recently discovered DarkerDungeons and wanted to use it in Foundry. I found and loved this module you made, but came across a few bugs, as well as wanting to use the Legacy sheet or Compact D&D Beyond sheet. I've put together a few bugfixes and compatibility tweaks to make your module's content show up on the Legacy, and Compact D&D Beyond sheets.

I'm not really a javascript dev, and it's my first time editing a Foundry module so hopefully my changes seem rational, let me know if anything is amiss. The Legacy compatibility is definitly a bit rough, but it at least provides the functionality.

Legacy Sheet Compatibility:

Added rudimentry validation when searching for elements to add content to. If the new sheet locations cannot be found, it falls back to using the Legacy sheet locations.

• DarkerDungeons tab now properly displays its contents on Legacy sheets.
• Added error handling to large portions of the inventory/encumbrance setup as it otherwise throws fatal errors on legacy sheets that prevent further sheet setup from executing.
• Added back the Wounds section to the Legacy sheets.

Bugfixes:

• Reopen Wounds Button not working: Fixed element classes being declared in two places in the element definition resulting in most of the classes being ignored.
• Fixed Reopen Wounds button reading ReopenReopen Wounds when hovered due to css style.
• Fixed Stamina Check button only being interactable when clicking the central text by moving element class up to the parent div.
