Ignore-this: 24e27a47ded6f7c60452ea89821ac710

A malformed message could crash the program. better just ignore and throw.

added new concept of introductions

Ignore-this: cb218e9fd71593c9ed9ec848a269aa10

The idea is that a contact can introduce you to another. This is another way for two
users to connect to each other instead of using contact files. The idea is that
you get a list of introductions from other people you can accept.

For this to work, i will have to implement message signing so that you can trust
that the introduction came from someone you already trust.

started to add GUI to show introductions

Ignore-this: 158ffe250baa1cf9816483783b3f4f9a

There is now a new introductions tab. You can see all introductions, remove them or
accept them.

You can also introduce a user to another. The introduce functionality isn't implemented
yet.

update message metadata to include security used for the message

Ignore-this: d11120ed5ba99d141a6fe67fd8114d46

You can now set encryption to be forced to a specific type. Also the encruption method is filled in when decrypting the message from the queue. This will make it easier to improve the security by allowing
a subsystem reject messages that are not of the correct security level.

Also fixed some silly mispelz

shouldn't be an assert here

added utility functions that throw if message with unexpected encryption arrives

Ignore-this: f9845be45a82aaff0a87de8039242685

This allows for services to easily make sure messages recieved were encrypted as expected.
This should prevent some DOS type attacks.

added support for sending introductions

Ignore-this: 6a3b566ae08f1cd772631f096a4e31a5

You can now introduce someone to another. The idea is that people in your contacts can
introduce you to others. This is another way to add a contact besides a contact file and
should help making it easier to add people to your contact list.

This commit has ui updates and backend to manage introductions.

What is missing is ability to select a greeter service to send along with the introduction.
