FEM: Disable "open editor" and "run ccx" buttons.

Browse Source 
This commit moves checking prerequisites to function. The function
is called before writing .inp file to make sure all required objects
are included in the analysis. "open editor" and "run ccx" buttons are
if check_prerequisites runs successfully.
