Revert "removing protocol relative url"

[asennikov]

Reverts #43

[asennikov]

Heu @mansona, I've merged your PR but then realised, that we already have support for setting protocol directly on demand.

See this old PR for details - #26 I'll add this info to docs.

[asennikov]

Actually, we already have it noted here - https://github.com/asennikov/ember-g-map#configuration

Coverage remained the same at 100.0% when pulling d6440b1 on revert-43-master into f41b665 on master.

@asennikov that seems like an extraneous configuration now that protocol relative urls are considered an anti-pattern? maybe having the default be https would be better?

Would you like me to put together a PR that puts the default as https?

[asennikov]

@mansona Yeah, you're probably right. Let's do another PR, but let's just make it though it won't break apps that are already setting src directly there.
