The most important change in this changeset is that InsetCollapsable::getLayout

is commented out, so that the documentclass is queried every time instead of
using the layout_ cache. For now I have kept the setLayout calls, but they are 
inoperant. 

Other changes:
 * remove non-const usePlainLayout methods
 * move InsetCollapsable::allowSpellCheck and allowMultiPar to InsetText
 * move InsetCollapsable::isFreespacing and forceLTR to Inset

Freespacing support could be moved to insettext, but I have to check who 
uses it.
