Handle HTTP 1.1 along with 1.0

[raustin9]

The server currently uses the HTTP 1.0 protocol where each connection is closed after communicating. This is less efficient and not up to current standards for servers.

Implement HTTP 1.1 by keeping a connection open that browsers can maintain communication on if they are using HTTP 1.1. If a client is using 1.0, keep the 1.0 implementation.
