Catch anything

[Vorkytaka]

We used the Exception class hoping to put a StackTrace in it, but in the end it all went to _Failure. For this reason we can catch any throwable now.

Or nah?

We made a test attempt to develop an inline Either, but it was not successful.
Here it is.

So, probably, it's better to do this task.

Ok, we did it with new PR #23.
But i'm not sure that i like it.

With this new way to catch exception we actually can use Result as an Either, and also can catch any kind of errors, but...
In all cases we need to set F generic, with what code looks too ugly.

I don't think, that we will merge this at the end.
