Error back

[leonardo2204]

I created this PR to address #32 enhancement.
My previous code from the #37 is also here, so, sorry for the long commit.
I'd suggest taking a look at 2c33eaf for code only of the #32 issue.
I managed the issue addressed by @zawadz88 :

When we go to the previous step? If so, when we then go back to the failed step the regular state should be shown instead of the error state?

Adding a showErrorStateOnBack flag, so the user can choose whether or not to clean the error from the current step when moving back.

The main point I'd like to discuss is when we get an error on "complete" state, do all the necessary steps to get it right and press "complete" again. Currently the callback is correctly fired, but the "error" state is never cleared. Not sure if this should be treated, as most of the cases the user will move forward to another screen.

What are your thoughts on that ?

Thanks!

Hi @leonardo2204,
Could you rebase these changes on top of the current version of master branch as the 'Further abstraction' code has been already merged? It's currently kind of hard to read the changes ;)

@zawadz88 Just did, but I think the changelog will continue.. Should I open another PR ?
