Storage and frame refactor (#1418)

Browse Source 
The purpose of this is to expose `frame.storage()` and `frame.storage_mut()` so users can save/load app state from the `App::update` function, without having to add another parameter to that function.

Changes:
* Added `Frame::storage()` and `Frame::storage_mut()`
* `App::update` now takes a `&mut Frame` rather than just `&Frame`
* `Frame` is no longer `Clone` or `Sync` (doesn't have to be since https://github.com/emilk/egui/pull/1366)

* Change default for `NativeOptions::drag_and_drop_support` to `true` ([#1329](https://github.com/emilk/egui/pull/1329)).
* Remove the `egui_glium` feature. `eframe` will now always use `egui_glow` as the native backend ([#1357](https://github.com/emilk/egui/pull/1357)).
* Removed `Frame::request_repaint` - just call `egui::Context::request_repaint` for the same effect ([#1366](https://github.com/emilk/egui/pull/1366)).
* Use full browser width by default ([#1378](https://github.com/emilk/egui/pull/1378)).
