remove the nightly requirement for lazy_static on no_std

[nivkner]

thanks to rust-lang-nursery/lazy-static.rs#130, lazy-static now works on stable with no_std

I believe removing a feature is a break-in change.

[nivkner]

yeah, I guess it is.
removed the commit, but since the nightly feature was only used for this,
it should be removed for 0.9

[AltSysrq]

Thanks for this!

0.9 is going to be the next version anyway, but I think it makes sense to keep the nightly feature since we may be adding stuff to it in the future again.

[nivkner]

@AltSysrq is there a reason why this PR did not get merged?
since as previously stated I removed the feature removing commit, this only removes its use for lazy_static.

[Centril]

@AltSysrq We have an unstable feature, so we should remove nightly in favor of that one (unstable is the standard name in the ecosystem).

[AltSysrq]

@nivkner I haven't had time to work on the next release yet, and I don't like things being in "merged/closed but not actually available for use". I'm planning on working on this next weekend so it will probably be merged then.

This has been incorporated into 0.9.0.
