Currently it seems to be impossible to run the following test setup due
to missing dependency declarations:
```
cargo test --no-default-features --features 'quickcheck'
```
This was first observed in petgraph#331.

Running the above fails due to multiple reasons which boil down to other
features being disabled which are actually necessary.

This PR aims to fix that by declaring a dependency list for the
quickcheck feature and is a revamp of petgraph#372. Thus, this resolves petgraph#331.

I am not 100% certain about the `std` dependency in the quickcheck
dependency list, but without that dependency there seem to be some
issues with missing RandomStates (std) to initialize certain structs in
quickchecks. Since furthermore Quickcheck does not have `no-std`, it
would - according to my understanding - include std anyways.
