Fixed multitouch input. Module is now exported with global functions hidden via MODULARIZE as global object OccViewerModule created by createOccViewerModule(). Global Module setup has been moved to occt-webgl-viewer.js. Use EMSCRIPTEN_KEEPALIVE attribute istead of listing C functions via EXTRA_EXPORTED_RUNTIME_METHODS. WasmOcctView now exports static methods as Module functions using EMSCRIPTEN_BINDINGS. Standard_ASSERT_DBGBREAK_() is now defined using emscripten_debugger().
