Add DBOPT_GUI_CAN_EDIT flag for defvars expressions

Nobody has claimed this yet.

Al Nichols requested this. Silo allows you to store expressions in a file. It allows you to 'edit' them if you want to also. Just read 'em, change their defintions and write 'em back out. Thats constrained to operate in the same way as all other Silo object edits; the object has to fit into the same or smaller space in the file. But, editing the expression stored in a Silo file is NOT what this enhancement is about. Its about hinting to a viz. tool like VisIt that the user would like the ability to edit the expressions in the tool's GUI. In VisIt, this would mean that the expression would not honor the check box in VisIt's expression window to show or not show db expressions. It would always be shown and it would never be greyed out.

Comments:

No file or test is named. Search the Silo C sources for existing DBOPT_* flags and defvars expression handling, then trace how option metadata reaches VisIt's expression GUI; done means the new flag is represented and produces the always-visible, editable behavior described in the issue.
