Exception catching mode

[gene-pavlovsky]

The issue is the same as in the tink_core ticket: haxetink/tink_core#165
Or will adding an exception catching mode to tink_core also fulfill the same purpose for tink_state?

I made a small test program which checks how it works with both signals and observables. The results are more scary than I thought. If any signal handler / observable binding throws an exception, not only this prevents other handlers / bindings from being called with the current signal / state change, but none of the handlers/bindings ever run again on further signals / state changes.

I reckon this kind of solution should fix the observables issue as well: haxetink/tink_core#175
