Tags system

Tags can be added to ANY javascript object (not necessarily reserved to BabylonJS) by calling BABYLON.Tags.AddTagsTo.
BABYLON.Tags.MatchesQuery can be used to check if a javascript object matches a "boolean" query:
   var myObject = {};
   BABYLON.Tags.AddTagsTo(myObject, "tag1 tag2");
   BABYLON.Tags.MatchesQuery(myObject, "tag1"); // => true
   BABYLON.Tags.MatchesQuery(myObject, "tag2"); // => true
   BABYLON.Tags.MatchesQuery(myObject, "tag3"); // => false
   BABYLON.Tags.MatchesQuery(myObject, "!tag3"); // => false
   BABYLON.Tags.MatchesQuery(myObject, "tag3 || tag1"); // => true
   BABYLON.Tags.MatchesQuery(myObject, "tag1 && tag2"); // => true
   BABYLON.Tags.MatchesQuery(myObject, "tag1 && !tag2"); // => false
   BABYLON.Tags.MatchesQuery(myObject, "(tag1 && !tag2) || !tag3"); // => true

   BABYLON.Tags.MatchesQuery(myObject, ""); // => true since it has at least one tag

   var myObject2 = {};

   BABYLON.Tags.MatchesQuery(myObject2, ""); // => false since it has no tag

   BABYLON.Tags.MatchesQuery(myObject, undefined); // => true
   BABYLON.Tags.MatchesQuery(myObject2, undefined); // => true

BABYLON.Tags.MatchesQuery doesn't use eval which is prohibited in win8

BABYLON.Scene.prototype.getMeshesByTags uses this system
