"not set" in xsCol is lost after 2nd save

[miloosh]

in all other cols is "not set" first in list and everything works as expected
but in xsCol

• "not set" with empty value is not first in combobox
• after save is in combobox preset first item "Auto layout"
• after another save "Auto layout" is saved

Can be fixed, sort of, by putting this line:

• array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.notset', ' '),

before this line:

• array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.autoLayout', 'col'),

In FlexFromController.php

not set option is now default, but the functionality is good now, it keeps the selected option active/selected.

Could this be included in the next version? We need to apply a patch for this issue in our projects.
