IdStory Identity Manager

I working on POC for universal system wizard. I try to using existing components from react-router.

I think this way is possible, but I found some new obstacles. For example I cannot get wrapped instance from redux component.

• Buttons form the step component can be added to wizard footer now.
• Some steps were redesigned - new step only for one mapping was added and extra new one step for attributes.

• Added readme and example for Basic.Wizard component.
• Wizard's button showLoading is controlled by showLoading on steps component now.

Wizard component and wizard for system creation is in the develop now.

I did test and code review, it works, thx! I like it, its awesome feature with minimum copied code. I like steps validation with auto focus.

I found some minor notes:
- "onEnter" event doesn't work on forms (maybe hidden submit button will fix it, but lookout for filters - "onEnter" works properly there now)
- padding for tabs is missing below info alert bloc in synchronization step
- linter warnings are in code - SchemaObjectClasses, SystemMappings, SystemMappingDetail etc.
- the last step with success alert with large icon - we can redesign it together somehow, if you want (padding, margin, icon and button placement).

Thanks for the feedback.

Support for onEnter will be implemented in the #2504.

I did test and code review, it's nice, thx!
