TYPO3 Core

Currently the excludefield selector displays the table name and field name in field label. Its sometimes hard to scroll to the specific table and fiend fields.

Do not display table name redundantly for each item but group items like
it is done for other fields like page types.

• Add header for each table of items in excludefields and remove table from item label
• Add possibility to set icon for headers
• Unset icon for page type headers
• Remove unused variable $descr
