[TYPO3-core] RFC: #9793: No way to hook into the publish process for a workspace

[Erik Frister]

This is an SVN patch request.

Type: New feature

Branches:
TYPO3_4-2 & trunk

Problem:
There is currently no way that we can hook into the version swap method 
for a given record in the tcemain.php. This is needed for the next 
commerce release; so that when a record is published (switched into the 
LIVE Workspace) we can also publish related records that would otherwise 
stay connected to the old version.

Example use:
A product is to be published; the product record has related attributes 
which refer to the product uid. Without the hook, when the product is 
published, the attributes are not informed of the version swap and still 
refer to the (now) offline version of the record.

Solution:
Implemented a hook in the version_swap method of the tcemain.
