TYPO3 Core

Often times there is the problem that a team works together on a project and another person jumps in. Now he checks out the main repository but does not have all submodules. He changes the index typoscript template where all static templates from the extensions are included and since he does not have all of them locally, he removed some without any notice. Then the project is broken.

Before saving the typoscript template, there should be a check if the static templates in the list do really exist and if not, a flash message should be shown that a static template has been removed.

This does affect ALL TYPO3 versions of course and should be backported until 4.5!!!
