Add convenient style configuration

[samirakhmedov]

What is the new or updated feature that you are suggesting?

In the current implementation the map styles is presented in String, which not only confuses newcomers, but confuses everyone else due to the fact that documentation to this thing is huge, and from the first try it is really hard to comprehend.

Why should this feature be included?

In order to set map style in more usable and flexible way, not to figure out what is needed over and over again.

Nevermind, there is a tool for configuration.
