openvpn ccd: Minor fixes: iroute, delete route line.

Fixed several bugs:

1) iroute line not correctly printed in ccd file
2) route line was not deleted from server.conf when deleting a client
3) Routebox (client has access to these networks on ipfire site) did not show green,orange and blue when no static route was defined on ipfire
4) Green is no longer selected as default route in clientconfig.

Tested all Options with Windows 7 Client and Linux Mint 12
