tower capture & abbot fix
fixed #58 - wrong nickname in pre-game chat
rules update - if a knight is removed from the city, the player may not
deploy or move any other figure.
Merge branch 'master' into release
release 3.0.2

* rules update: taking prisoner is now not mandatory
* rules update: The placement of a princess tile (Princess & Dragon)
with removal of a knight
   from the city cannot be used as a first “follower move” and be
followed by placement
   of the Phantom (e.g. into the now-vacated city). As per the rules for
the princess,
    “if a knight is removed from the city, the player may not deploy or
move any other figure.”
