Harald JOHNSEN:

- model.cxx :
  load the 2.5D panels before the animations so that the panels can be used in
  animations his solve the problem of 2.5D panels visible outside of the
  aircraft (one can add a null animation to put the panel at the top of the
  aircraft graph so it is drawn first) and this adds the possibility to have
  billboarded/popup panels.

- newcloud.cxx :
  removed 'this' pointer cast for amd64 compiler.
