Extract AbilityScores out of MainSheet
Define two Font sizes in Sizes

So that way, hopefully they should be easier to change. Although
who am I kidding - any change will completely break the layout.
Give ValueBox innerTextTop property

There's now a Text field at the top left that's only visible when
that property is set.
Make ability scores actually display the stats

I forgot to actually set the model for the main repeater.
Extract Hit Points are to its own file
Extract Armour Class Area into its own file

And actually make it work this time.
Fix up the alignment of MainSheet

Use anchors instead of Row because AbilityScoresArea doesn't line
up with mWidth().
Create base Area class

Primarily so that I can toggle the borders on/off.
Minor fixes for AC area
Create touch/flat-footed AC area

Man that was a pleasant row.
Create Saves Area

All in all, things worked out okay.
