g++ 4.2 (and possibly earlier) apparently call a copy
constructor when passing a temporary to a function
that takes a const reference. Added code to allow
copy-constructing the AI*Access classes for this
compiler.
g++-4.2.x also bails out when it encounters files that
do not end on a newline. So, also added those where
they were missing.
Emerald physics demoted to legacy. Only enabled on av's that fail to send physics paramaters, or AvatarPhysics is completely disabled.
Params reset when AvatarPhysics is toggled off. (Bugfix for LL's code)
