Correcting a recently introduced bug in nonlocal isotropic damage material.
Added documentation to axisymmetric elements. Updated unv2oofem for 1 axisymmetric element.
Added tests on linear axisymmetric elements for sm module.
Fixing generation of html version of elementlibmanual
Fixing store/restore context methods (adding missing variables), added preliminary support for load balancing (not calibrated)
Fixed nrsolver convergence checker if there are slave dofs in use.
A few input record fixes.
Removing a few util.h functions which have been superseeded by C++ alternatives (from std).
Making input records only use string literals for field id.
( optionally, locally scoped enums/integer/hashkey identifiers could be added if it is shown to be necessary for performance, see discussion on forum for details )
