PointerTo warning when compiling with MSVC 2010

[ponyboy837]

Panda3D seems to output loads of inlining errors on the latest 1.10.0 version such as

panda\panda\src\express\pointrTo.h(73) : warning C4141: 'inline' : used more than once
panda\panda\src\express\pointrToBase.h(34) : warning C4141: 'inline' : used more than once
        panda\panda\src\express\pointerTo.h(69) : see reference to class template instantiation 'PointerToBas
<T>' being compiled
        with
        [
            T=VirtualFileMount
        ]
panda\panda\src\express\virtualFileSystem.cxx(209) : see reference to class template instantiation 'P
interTo<T>' being compiled
        with
        [
            T=VirtualFileMount
        ]
panda\panda\src\express\pointrTo.h(73) : warning C4141: 'inline' : used more than once
[ 8%] Building Interrogate database built/pandac/input/libp3express.in

This seems to be a issue with multiple inlining statements in the pointerTo files. Please do look into this.

Fixed now, although we may end up deprecating MSVC 2010 soon in favour of MSVC 2015.
