Rotatable blueprint

Add ability to rotate block on saving in Blueprint.

Changes:
+ Change Blueprint gui: add buttons to manage angle of rotating on every axis;
+ Blueprint content rotates clockwise if look from point {0; 0; 0};
+ Separate Nametag gui.

PS. I didn't done everything that I wanted. But its already can be used.
