Updated for building on visual studio 2012. Changed it so that some compiler setting are set for all visual studio versions from a certain number and up (depends on the setting).
Also made sure that the libraries will be correctly named for future visual studio versions without further updates.

Updates to Find*** modules as well to automatically append the correct suffix for our libraries built with future visual studio versions without updating module again.

Made sure that wxWidgets is not required when using H3D_USE_DEPENDENCIES only build.
