WIP spellcast section and other minor tweaks

WIP checkin for spell casting section revamp.  Also removed tables from
weapon and armour sections.  Will need restyled when going through sheet
later.
Completed spell section

Working, but basic and un-styled version of the spellcasting section now
complete.....still needs some polish but can do that in next pass.
Coin and Weight limit section reworked

A messy but functional coin and weight limit section of the inventory is
complete....as usual will need a style pass for a tidy as it's
functional but messy at the moment
