Improved Gas UX (Pt. 1 - Gas Slider on Send) (#728)

* Initial crack at simple only gas slider component.

* Work on advanced component. Refactor redux and components to specify gas limit vs price.

* Convert fee summary to a render cbesque thing.

* Rework responsive columns.

* Remove force offline button.

* Tweak styles.

* Fix tscheck issues, remove unneeded prop.

* Fix references to GasField

* Gas slider in lite send.

* Make gas slider network-aware for symbol and price calculation.
