Fix DirChooser/FileChooser private bookmarks.

[GB.FORM]

• BUG: force rechecking of items in DirChooser when setting private bookmarks

Notes..
I add a ForceCheck optional boolean to the CBookmarkList.Load method Then it does not return and rechecks after setting private bookmarks.

also it does not work unless I uncomment FillMenu from DirChooser.SetPrivateBookmarks
