A few changes in the Level Selector Plugin

[hmoraes]

Hello

I made a few changes in the code to resolve some problems I had. Below I will list them:

• The Level Selector remains visible when Media Control hides
• It is possible click in the selected level
• The label was not showing the actual playing level correctly
• Show the Level Selector only if it has at least 2 levels

I appreciate your work, it was very useful for me.

Thanks
