Title: Relax addressable requirement

Trying to use dm-core HEAD failed for me because:

```
Bundler could not find compatible versions for gem "addressable":
In Gemfile:
dm-core (>= 0) ruby depends on
addressable (~> 2.2.6) ruby

launchy (~> 2.4.2) ruby depends on
addressable (2.3.5)
```
This PR relaxes the addressable requirement. Before and after this change I was getting 3 spec failures.
