Comments every methods in every header

But introduces a bug: sometimes seg fault

Add ERROR_AUTHENTIFICATION and ERROR_NETWORK to the account state

Registration possible if the account is in ERROR state

Adding error state
Global variables on the client side moved in sflphone_const.h

Problem: the window doesn't refresh

But no persistence for prefered account (order)

Actual behaviour: you can select an order of account, the first in the list is the one used to make calls
If this one isn't registered, we loop on the rest of the list and call with the fisrt registered account we encounter

OK if : 1 SIP account
	1 IAX account
	1 SIP and 1 IAX account

Still can't unregister!!
