TYPO3 Core

Problem:
Currently the ExtDirect API generator doesn't differ between HTTP and HTTPS.

Solution:
Add the TYPO3_SSL environment value to the cache hash for the generated ExtDirect API hash value.

How To Test:
1) Call the backend with HTTP
2) Call the backend with HTTPS (don't clear the cache)
-> this will raise some errors in your debug console, because of wrongly called ExtDirect calls
3) Apply the patch and reproduce steps 1 and 2
-> this time you won't get the mentioned errors and anything works like expected
