A lot of changes:

	- metric is 3 byte long now
	- summary lsa originating
	- more OSPF areas possible
	- virtual links
	- better E1/E2 routes handling
	- some bug fixes..

I have to do:
	- md5 auth (last mandatory item from rfc2328)
	- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)
	- 2328 appendig E
