renamed sessin to conversation

Ignore-this: a4e1a12fc81584b7bd95125a1ce0af2a

After some usability testing the concept of "session" was difficult to grasp.
Using the term "conversation" seems to be easier to understand.

This change is NOT backwards compatible as the protocol changed. Doing things like
this early before having many users is a good idea. :-)

fixed bug where events were not shown in session

local events are not encrypted. note, need concept on local message
instead of remote to make sure messages from outside to not cause events!

added more security by expecting messages to be remote or local

Because events may go through the same mailboxes as other messages, it is wise
to determine if a message came from within the system or outside of it from the outside.

Each message handler can expect either a remote or local message and expect a certain
type of encryption if it is remote.
