Add support for Bar and BlueScreen Debugger dependency injection

[bacinsky]

I wonder why there is no way to set Tracy\Bar and Tracy\BlueScreen into Tracy\Debugger via setter dependency injection. It will be nice to have such a possibility. Now it is barely possible with class_alias() or maybe different workaround.

Just want to know your opinion, for now.

Why problem are you trying to solve?

[bacinsky]

I think the DI solves both issues, disabling the Tracy Bar and even its customization. Injecting the BlueScreen object will be nice too. Tracy is for developers, it should be. Maybe time to introduce interfaces for some interchangeable parts?

[JanTvrdik]

I hate when people use RFC without doing anything that would classify as RFC (evaluating of current situation and explaining what is wrong with it, proposing a solution and explaining why it should be accepted, what is the impact on backward compatibility etc.) Maybe we should stop using the RFC word at all.

[bacinsky]

My bad, but I'm trying to get some attention on this issue before I put more effort to and it works. I'll try to get some time on learning how to write a RFC, you can close this, if you want. I can handle it.

[fprochazka]

@bacinsky more appropriate would to remove the word from the issue title.

[JanTvrdik]

I still don't know what are you trying to solve. What do you need to customize? How would you solve #82 with this?

Simply nobody needs it. And things that nobody needs, I am not implementing.
