Move application files to your own folder

[lex111]

E.g, in app or src. It's allows you to distinguish applications from RN files, and also to be able to search the entire app, because now everything is to the root folder.

@ovr what do you think?

Let's use src, but it's not a big deal for me
but looks better for development when you find something by folder

[lex111]

I also like src, I'll try to do it.
