Add the weight bar

[adacosta92]

Add a bar to show weight carried (especially with variant encumbrance), just like in the default character sheet (on the right, at the bottom of the sheet)

D&D Beyond automatically handles encumbrance, unlike Foundry.

Variant encumbrance is fair. But normal encumbrance should already be supported with the simple weight number above the inventory list.

I suppose it wouldn't hurt to make the bar an optional thing, I personally do not like how much space it eats for something which is so small a part of many games.

I'm probably never going to get around to this, sorry.
