Title: Bugfix: The function "exif_imagetype" doesn't seem to be available at every system. So we emulate it.

There was a reporting that the "fromgplus" addon and the new twitter connector don't work at a system at "uberspace". We found out that the function "exif_imagetype" isn't available there.

There is a function that is doing nearly the same. The missing function is now emulated.
