TYPO3 Core

There are several more bugs that are related to issue #50913 in TYPO3 4.5 which will fill the sys_log database.

In the official php documentation explode must have at least two parameters that must be of type string.
I found this issues in the TYPO3 4.5 Project that does return php errors because of giving NULL or integer values to the trimExplode method of the t3lib_div class.

Perhaps there could be even more bugs, i did not found yet. Therefore i fixed the trimExplode method as well.
