Feature: Integrate navigation drawer

[m4gr3d]

Updated the app to use the navigation drawer for primary navigation:

As a side effect to the ui update, the 'Settings' and 'Drone Setup' sections were merged together. The 'Settings' is now the parent activity, and 'Drone Setup' is launched from the 'Settings' screen:

For now the 'Drone Setup' user interface was left unchanged.
I'm awaiting feedback from @DroidPlanner @arthurbenemann and @jason4short as this could be the first step toward completing @jason4short 'Drone Settings rework' issue (issue #626).

I haven't run it yet (working on the decoupling branch), but the screenshots look great. I like the settings menu, with app settings in the parent activity. This makes us a lot closer to the Android design guidelines, which is nice.

Do you want to work more on this or should I merge it?

[m4gr3d]

I wanted to get @jason4short 's feedback regarding the drawer's look, but it's good to merge as is.
Also now, the menu only contains activity's specific action items. All the navigation was moved to the drawer.

[m4gr3d]

But feel free to go ahead and merge it.

Looks good.
Maybe we should also change the Edit icon on the bottom to say "Editor" like your panel shows.

Just tested it and it works very well.

I'm just thinking that the editor should receive a promotion to top at the navigation hierarchy.

[m4gr3d]

@arthurbenemann the FlightActivity 'Edit' button implies the 'Editor' activity is a subsection of the 'Flight Data' activity, hence its place in the navigation drawer. If the editor is promoted to the top, will it still be accessible via the 'Edit' button?

[arthurbenemann]

Good point. I would like to promote the Editor, but that shortcut button really implies a child in the hierarchy.

@jason4short Any comment's on this issue?
