Update plugin layout to match other content elements
In TYPO3 4.5, we have a new layout for built in content elements and plugins. FE Login is a bit of a hybrid since it is a frontend plugin but replacing the old built in content element. To achieve this, it overrides the TCA showitem definition of the old login content element. This showitem definition should be updated to the 4.5 layout.
