[RDY] Added support for Custom Exception Handler

[ideallical]

This PR makes it possible to enable DRF's custom exception handler, by default the old behaviour is kept for backwards compatibility. Typo has been fixed.

[blueyed]

Please add tests for it.

[ideallical]

Should be ready for merge now, @blueyed

[blueyed]

Thanks!
Can you rebase it please, so we can see how #382 has an impact?

[ideallical]

the branche has been rebased @blueyed
Somehow, the codecov plugin doesn't appear in this thread (although it's being used in Travis). Shall I close this PR and create a new one to see if that helps? @blueyed

Maybe re-opening helps for codecov.

Otherwise I've thought that I've left a comment for this to be the default, but have not?!

[blueyed]

See also #386.

[ideallical]

So, coverage report says coverage went up. Time to merge? @blueyed

[blueyed]

@ideallical
Thanks, but I think this should be just the default, without a setting for this.

[blueyed]

@jpadilla ?

[draskomikic]

Hi guys, I am also interested in this feature, when do you expect it will be merged ?

[ilstreltsov]

@blueyed
Making this behavior (raise exception) as default will break backward compatibility, right? So i suggest just to merge PR as it is. Up!
