           Summary: [UNIX] Increment/decrement module load conter in
                    NetscapePluginModule::getPluginInfo()

Since the method is static, we are using NetscapePluginModule::getOrCreate() to get the module. If it's created, the load counter is 0, so that when module is deleted, shutdown() hasn't been called and the destructor crashes in the assert that checks the module has been removed from the initialized module list. We should increment the load counter, and decrement it before getPluginInfo() returns, so that decrementLoadCount() will call shutdown() if counter is 0 and the module will be deleted from the list.
