Cachebust feature

[FaisalAbid]

Related (and dependent) to my previous pull request, but this enables auto cache busting by passing in

bust_cache: true
bust_cache_key: "dartcache"

into the transformer arguments in pubspec.yaml.

bust_cache_key is optional.

I'd love to merge this and then cut a 1.0. Can you please fix this and rebase?

@FaisalAbid Ah, sorry to conflict with this work!

What do you think about an approach that makes use of Uri.parse? That may be more robust than the regex I wrote or manual String splitting.

[FaisalAbid]

Hey, yea Uri.parse would be better. I'll clean this up tonight

@greglittlefield-wf
@FaisalAbid
shall we get this cleaned up and reviewed?

[FaisalAbid]

yea totally this needs to be done. My tonight never happened :P I'll try to take a look at it this weekend.

This is a nice addition, but hasn't been touched in quite some time. For now, we're going to close this pr but remain committed to assisting in any way possible, should this pr get reopened and the merge conflicts resolved.
