Create new improved error dump

[icanhazstring]

Followup to #246

For the newest release, I removed the error dump feature as it needs major reworks.
To better understand was is happening under the hood some kind of event system is probably the best way to hook into every step of the workflow.

ACs:

• Create a new EventDispatcher which should be injected in the correct places to dispatch new events
• Create an EventListener that will be called upon certain events and attach content to a dump file

@icanhazstring I reviewed commit about clean up code when the event dispatcher was removed. Can I use https://github.com/symfony/event-dispatcher for this ?

What about displaying progress bar ? Previously the IO was injected directly to the parser classe. Does the implementation of progress bar should working on event-listener feature ?

[icanhazstring]

There is an open issue about bringing back the progress bar. Maybe something good to start 😉

#320

[MarcinGladkowski]

In #320 you wrote that the progess bar will be reimplemented in this task (#271). Looks like circular reference ;)

[icanhazstring]

We probably should do dumping here and progress bar on the other 😉
