issue: #185: use revealLine for line update

[aghArdeshir]

This PR fixes #185

The solution was to use revealLine instead of setScrollPosition (which works with pixel values instead of line)
Also as it turns out, there are 3 methods: revealLine, revealLineInCenter and revealLineNearTop. I'm not sure if it's a good idea to add this complexityto Editor's props or to choose a different default behavior for monaco-react library.

I agree we don't need revealLineInCenter and revealLineNearTop as props. The user has access to editor instance, so, if they need a custom solution instead of the default one, they always can do it using editor instance.
