[TYPO3-core] RFC: #17777: t3lib_extMgm::addToAllTCAtypes(..... , 'replace:xxx'); break when palette used in many types

[Tolleiv.Nietsch]

This is a SVN patch request.

Type: Bugfix

Branches: trunk, 4.5

Bugtracker reference:
http://bugs.typo3.org/view.php?id=17777

Problem:
Hard to explain - see attached unit-test. The 
t3lib_extMgm::addToAllTCAtypes() produces invalid output when used with 
the 'replace:xxx' parameter in case the "xxx" field is on a palette and 
if this palette is used in more than one type (e.g. the "layout" palette 
in the pages table)

Solution:
Save the list of modified palettes and avoid that the fields are added 
to the showitems in case this palette is used elsewhere too.

Ways/ steps to reproduce:
A) See the unit tests and how nice the break if the patch is missing ;)

B) Install templavoila, see that the pages.tx_templavoila_to field on 
shortcut pages is present on the appearance tab (within a palette) and 
also added to the extended tab.

Cheers
Tolleiv
