[TECHNICAL-SUPPORT] LPS-33282 Page sorting in navigation has no permanent effect without UPDATE permission

Hi Tamás,

These variables ("updateable", "deleteable") are used in navigation.js (check method "initializer" from line 87).

If "updateable" is set to "true", drag&drop sorting can be performed on client-side, however, it won't have any effect, since this action requires UPDATE perm. (LayoutServiceImpl.updateLayout())

Please, review my changes.

Thanks,
Tibor
