Wheezy-ignore tag for freecad and netgen

[Anton Gladky <gladky.anton@gmail.com>]

Dear release-team,

please, consider a granting a wheezy-ignore tag for bugs
#617613 (freecad) and #618968 (netgen).

Both bugs are license issues, which are, seems to be "fixed",
but not in Wheezy. It is impossible to make a new uploads now
to correctly close those bugs.

Thanks,

Anton
