Merge branch 'umode-B'

This patch series allows ngIRCd to support the user mode "B" ("Bot flasg"):
it is settable and unsettable by every (non-restricted) client.
According to DNS777, this is how Unreal and InspIRCd do behave, so do we :-)

By Alexander Barton (1) and DNS777 (1)

* umode-B:
  Add new user mode "B" to doc/Modes.txt
  Implement an Unreal-like user mode "B" ("Bot mode")
