1. Added specific header files to disable and restore compiler warnings: Standard_WarningsDisable.hxx, Standard_WarningsRestore.hxx. (Currently only MSVC compiler is handled.) 2. Inspector: compiler warnings are disabled for all includes of Qt headers. 3. Inspector: minor code correction to avoid warning due to use of floating point values in integer calculations.
