simple access of saws from main.js

Merged master into barry/update-xxxviewfromoptions

added PetscViewerDrawSetDrawType() and PetscOptions[Get]Viewer() support for -viewer_type draw:tikz

fix examples that did not compile with complex numbers using Microsoft compilers
Microsoft compilers are very picky about complex number usage

Merge branch 'barry/fix-complex-examples'

moved petsc-solver-selection js code into PETSc try at saws/js

fixed (void*) caste to (char*) cast for malloc of string in PetscStrdup()

move SAWs push and pop header and body for options into PETSc library

updated to new version of saws and latest PETSc master branch

Merge branch 'barry/rm-strdup' into barry/saws-options

updated for new SAWs interface for pushing and poping bodies and headers

removed strdup() usage from code since it is not fully supported on solaris

Merge branch 'barry/remove-strdup'
fixed bug in previous version of branch that caused SAWs to crash

comment code to make sure malloc and free are not wrongly replaced with PETSc versions

Revert "removed direct use of non-portable strdup"

I forgot that these must be pure mallocs since SAWs may free and remalloc them

This reverts commit 77b82169ce741be1f9ad766c5deaa64f2b843e90.
