Updated for LBE 5.4.8088

updated german "arrays.xml", "plurals.xml" and "strings.xml" for LBE
Version 5.4.8088. This might cause problems with older versions of LBE.
I will maybe be updating the missing lines for the older LBE versions
after some feedback. Credits goes to "Hen Ry" ill took his translation
to update here! Thanks Hen Ry for your acceptation of using it.
