Title: Optimized for V8

1. Exchanged the method 'matchesSelector' to newer (according to spec) 'matches'.
2. Defined prototype methods using defineProperties to force them to go into "fast object"
Fast object: accessing the property in time O(1).

3. Freezed the Bragi object (using Object.freeze) to force it to not enter the hash-table mode.
4. Cleaned up the code a little bit - seperated some functions.
5. Some other minor changes.
