[TYPO3-core] G/T-MENU_LAYERS and Opera

[Martin Kutschker]

This is a CVS patch request.

Type: Bugfix

Description:
The patch detects newer versions of Opera and makes use of the improved interoperability. Layer menus will work now with 7 and 8, and may work with 5 and 6 (if you set height and with with CSS).

Branches: HEAD, TYPO3_3-8 (TYPO3_3-7?)
