Checkboxes for Boolean and non Boolean fields

Grid automatically shows checkboxes for Boolean fields.

To show checkboxes for no Boolean fields, fill first line of Column.KeyList property by value (or values) that corresponds to the checked state of the checkbox. Fill second line for non-checked state, and set Column.Checkboxes property to True.

One line of KeyList can contain more than one value. In that case every value must be separated by semicolon.
