core: rework actions and a bit of drawables, closes #2492 In the effort of having as less as possible memory allocation in libcore, the usage of actions and drawable no longer copy the original source parameter to let user pass a heap allocated variable or a static storage one. Update predefined drawable and actions to match these new needs.
