Title: Make edit/searchtype of select to handle optgroups.

When using edit type of "select" (and also toolbar search) I need to have my options groupped in optgroups.
I've modified jqGrid a bit to handle that.
It handles:
{
'Option 1': {
'val1' :'Sub1', 'val2': 'Sub 2'
}
}

currently it handles:
* form editing
* toolbar search
* cell formatter

it should be rewritten to use the same routine for building html select, I guess?
