Automatic created names for menu entries could be in camel case

Currently, the automatically created names have spaces replaced with underscores. As Qt propagates camel case (which I find more readable) it would be useful if the created names were in camel case. This would imply better named slots - with only the prefix and suffix separated by underscore.

Example: on_actionThis_is_my_main_menu_triggered would become on_actionThisIsMyMainMenu_triggered
