Unable to import macros individually [regression]

[andy128k]

With 0.11.0 release it is again required to write #[macro_use] extern crate juniper;. With version 0.10.0 import of macro worked well.

Bisect shows this commit as a reason.

Partial fix: #298 , but I'm still investigating some other errors with 2018 edition crates.

Also looks like #251 wasn't properly rebased, we should check if anything else got dropped.

FWIW this was the commit in 0.10.0 that added macro importing support: d496220

Ah also I just discovered: since we bumped minimum to 1.30 anyway, we can stop using local_inner_macros and instead use the $crate:: method as described here: https://rust-lang-nursery.github.io/edition-guide/rust-2018/macros/macro-changes.html

Ok I believe the macro issues should be fine now (in the PR).

Except a for a problem with the custom_derives in 2018 edition crates:
the module import hack we use in custom derives to make them work both inside and outside of the juniper crate fails.
The use_everything macro somehow does not work properly anymore and none of the types can be found.

Fixed and published as 0.11.1.
