Make adjustments for #32

[tyoung-99]

Adjustments needed for #32:

• [x] Move name/classes to new line if too long on char list
• [x] Fix calculation for attack/damage - calculating w/ decimals currently
• [x] Add empty note for equipped weapons/consumables, inventory items/treasure if none equipped
• [x] Adjust profs display to combine grouped profs (simple/martial weapons, light/med/heavy armor)
• [x] Allow no current concentration (errors currently if none)
• [x] Add support for bullets/other formatting in text areas, not just paragraphs
• [x] Make skills reach page end

Putting formatting support on hold until editing added. Will be easy to implement w/ react-draft-wysiwyg (can convert to JSON for easy storage).
