[BUGFIX] Fix usage of TYPO3.Storage JS and Tabs.js

The Storage module must be required as dependency in modules as usual.
The module itself has to take care whether a global object
is already present. If this is the case, the global object is used.

Additionally the Tabs.js is fixed to work again.
