Logo filter(s) now takes a list of images, delays and alpha as input and 

loops through these. The syntax is <file>[,[<delay in ms>][,[<alpha>]]][;...]
Idea (and some parts of the code) by markfm

Note:
The vout-filter segfaults upon destruction but i don't understand why...
could someone have a look ?
