Add support for page refreshs

[npehrsson]

If you refresh the page today the current resource will be lost, we should track the current resource in location.hash to prevent that.

Need to consider #44 when implementing this.

[npehrsson]

I've been waiting for this over a year :)

[nranas]

Are you finally implementing this @hfjallemark?

[hfjallemark]

I think @magahl already started implementing it.

[magahl]

I did? Maybe @robcar did?

@Edgar-Cordova aren't you going to fix this after the table rules redesign?

[Edgar-Cordova]

@pdiazdumont Yes, after releasing the new client without hypermedia.
