[TYPO3-core] RFC #10011: New feature: TypoScript Condition to check for installed extensions

[Steffen Ritter]

Has there be any agree after the discussion?
@Franz: Should this one be dropped?

besides +1 for the idea to me,
+1 on reading and testing Dmitry's version (to me it's cleaner and "more 
obvoius")

would be easy usable for extensions providing TS-Setup which may 
conflict with others... (Such as Extensions modifiying tt_content.*)
