[TYPO3-core] RFC #16074: Add new API t3lib_befunc::helpTextArray and use it in the ExtDirect tooltips

[Ernesto Baschny]

Hi,

This is a SVN patch request.

Type: Cosmetic / use API

BT reference: http://bugs.typo3.org/view.php?id=16074

Branches: trunk

Problem:
Currently the ExtDirect which fetches the tool-tip for CSH fetches the
information on its own from the $TCA_DESCR array. It will also render
"TYPO3 Inline Help" as a default header if none is given and will not
render an "arrow" which used to symbolize a link to a pop-up in its content.

This is a follow-up to #16059


Solution:
This patch adds a new API function t3lib_befunc::helpTextArray which is
then used by t3lib_befunc::helpText and also the new ExtDirect call to
fetch the information.

The tool-tips now won't have a title anymore if there is no "alttitle"
defined.


How to test:
Almost none CSH uses "alttile", so usually you won't see any. There are
some examples in the Extension manager (e.g. the main titles "Loaded
Extensions" etc).


Cheers,
Ernesto
