From Jan Peciva, Added write support into Inventor plugin.

Browse Source 
Note from Robert Osfield.  A couple of lines of code in ConvertToInventor.cpp
would not compile under g++ 4.1.2, so rather than hold back the dev release till
this is resolved I've optional compiled out the problem section.
The #define DISABLE_PROBLEM_COMPILE_SECTIONS is used to compile out the problem
section, this define is add via the CMakeLists.txt file.
