Added a new dispatcher for request handling.

It was designed to handle about a million and half requests
in a set of 2 thousand business requests registered in context.

All tests were run in a Core i5 2400 - 3.1Ghz with 4GB DDR3 RAM.

Note that routing packages still broken. It was an emergencial commit,
to delivery a high quality dispatcher. Compiling issues in routing package
will be fixed in the next commit.
