Text
Item text.
Selected
Item selection flag. There must be only one item for which Selected is equal to 1.
Checked
If nonzero, a selection mark is displayed before the item text.
If Checked is 1, the standard mark is displayed, otherwise the value of Checked is used as the
mark character.
Separator
If nonzero, the menu item is displayed as a separator line.
The other fields are ignored in this case.
As the FarMenuItem.Text field is large, direct initialization of an array of
FarMenuItem structures can significantly increase plugin size.
To prevent this, the InitMenuItem non-standard structure can be used.
