Migration from RxSwift 1.9 to RxSwift 2.0 version

The migration should be pretty straightforward. The changes are mostly cosmetic, so all features are still there.

• Find replace all >- to .
• Find replace all "variable" to "shareReplay(1)"
• Find replace all "catch" to "catchErrorJustReturn"
• Find replace all "returnElement" to "Observable.just"
• Find replace all "failWith" to "Observable.error"
• Find replace all "never" to "Observable.never"
• Find replace all "empty" to "Observable.empty"
• Since we've moved from >- to ., free functions are now methods, so it's .switchLatest(), .distinctUntilChanged(), ... instead of >- switchLatest, >- distinctUntilChanged
• we've moved from free functions to extensions so it's now [a, b, c].concat(), .merge(), ... instead of concat([a, b, c]), merge(sequences)
• Now it's subscribe { n in ... }.addDisposableTo(disposeBag) instead of >- disposeBag.addDisposable
• Method next on Variable is now value setter
• If you want to use tableViews/collectionViews, this is the basic use case now

viewModel.rows
            .bindTo(resultsTableView.rx_itemsWithCellIdentifier("WikipediaSearchCell", cellType: WikipediaSearchCell.self)) { (_, viewModel, cell) in
                cell.viewModel = viewModel
            }
            .addDisposableTo(disposeBag)
