TYPO3 Core

The recycler needs refactoring. This was done:

• use pageRenderer methods for including scripts
• use pageRenderer methods for inline settings and localization

• move plugins to t3lib (they should be shared for other components as well)
• split the object in namedspaced pieces
• remove unused vars
• rename vars to speaking names
• better usage of scope and addressing objects
• use template for confirm window

• use t3skin styles instead of own one
• remove doubled border
• add padding to confirm window body
