99dba69c87 Only add transport properties and keys when the contact was added 
This will be changed once we have a way to reset state for peers
that were contacts already at some point in the past.
One contact might have deleted the other, but not vice versa.
So they have mismatching state that needs to be reset.

See #2 for more information.

337f7e7b8f Unify introduction response methods and handle ProtocolStateException 
It is possible that a remote DECLINE message arrives short before the
user responds to the introduction.
This will cause a ProtocolStateException which (for now) is just caught
and a generic (existing) error message will be shown.

f8f98ed95d Properly handle DECLINE messages in START state 
Previously, DECLINE messages let directly to the START state
for introducer and introducees.
So incoming ACCEPT and DECLINE messages needed to be ignored in START state
introducing undefined behavior into the protocol.

This is fixed with this commit by adding two additional states
to the introducer state machine as well as making use of the existing
LOCAL_DECLINED state for the introducees.

bd5504de26 Add a MAC to the ACTIVATE message to prevent the introducer to fake them 
A fake ACTIVATE message would cause us to activate the transport keys
before the contact has received our auth message,
which would compromise forward secrecy.

0e04044ebb Ensure that incoming messages are expected in the current state 
Previously, the introducer would process and forward invalid messages by
the introducees. This commit adds the necessary checks and tests.

b291fcd2cd Only allow new introductions in START state 
When the user attempts an introduction, instead of the introduction
message input field, an explanatory text will be shown and the
introduction can not be made until the last one has been finished.
