Replace the Speex license tab in the about dialog with one that lists
all used libraries and their respective licenses, including Speex.
Previously only Speex required including the license in binary
distribution; the recently added bspatch also wants this. Show
the license for all used libraries so we can more easily add new ones in
the future.
