Subject: Updates to epee HTTP client code   - http_simple_client now uses
 std::chrono for timeouts   - http_simple_client accepts timeouts per connect
 / invoke call   - shortened names of epee http invoke functions   - invoke
 command functions only take relative path, connection     is not
 automatically performed
