Edits to Weapons, minor rearrangement of other skillboxes

Changed weapon section to use collapsible hard-coded weapons instead of fieldsets to allow usage in external macros.  Added code to try and keep skills where they belong instead of allowing them to slip below the left column when the window became too narrow.  moved feats/racial/class ability boxes back to the right column, fixed some typos, added CSS support for the collapsible weapons, updated json instructions.
