Wear os scenes and scripts support

[leroyboerefijn]

Summary

Updated HomeActivity to contain a recylerview that displays:

• Scenes
• Scripts
• Logout

All can be activated by clicking.

Note: currently there is no support yet for custom icons, the IconDialog cannot be used to get an icon by it's mdi name string as far as I can tell. The only alternative I could find () requires a Github Access Token. Any ideas to solve this are welcome :)

Screenshots

Any other notes

Next step is to add tile support. This is a bit larger change, since it requires to save a list of (favorite) entities in a db

This is great, I wonder if we should consider getting ready for the play store after this PR? Seems like we will have enough for beta testers to get started!

As far as the icons go I konw the dialog has a search feature and it seems to actually match MDI so not sure if we can invoke that from there or maybe MDI assigns a ID to each icon and thats what the library has?

Edit: We also have #1756 I think either one would be a good candidate :)

I looked at the source of the library. They do have tags, but I'm not sure if they match MDI. In any case, I couldn't find an interface to really go from the tag to the icon, but maybe I'm just missing something?

Getting beta testers involved would be awesome! I think it would make sense to have both PRs merged before doing that. Maybe even an additional small one with some minor usability things?
