Experiment with shorthand / single attribute macro

[StrikeForceZero]

More idiomatic

#[auto_plugin(...)]
#[auto_component(...)]
#[auto_resource(...)]
#[auto_system(...)]
#[auto_event(...)]
#[auto_observer(...)]
#[auto_system_set(...)]

More aggressive

#[auto(type = Component, plugin = Test, register, name)]
#[auto(type = Resource, plugin = Test, register, init)] 
#[auto(type = Event, plugin = Test, register, add)] 

[StrikeForceZero]

or maybe even a auto_target_plugin attribute macro to reduce redundancy

#[derive(Component, Reflect)]
#[reflect(Component)]
#[auto_target_plugin(plugin = MyPlugin)]
#[auto_register_type]
#[auto_name]
pub struct FooComponent;

expanding into

#[derive(Component, Reflect)]
#[reflect(Component)]
#[auto_register_type(plugin = MyPlugin)]
#[auto_name(plugin = MyPlugin)]
pub struct FooComponent;

[StrikeForceZero]

#[auto_component(
  plugin = MyPlugin,
  derive,
  reflect,
  register,
  name
)]
pub struct FooComponent;

Expands into:

#[derive(Component)]
#[derive(Reflect)]
#[reflect(Component)]
#[auto_register_type(plugin = MyPlugin)]
#[auto_name(plugin = MyPlugin)]
pub struct FooComponent;

[StrikeForceZero]

#[auto_*()] added in v0.5.0

experiments for #[auto(...)] pushed to v0.8.0 milestone
