Update docs ahead of 0.12.5 release

…ude host

Unsafe dj.kill() added to facillitate usage by automatic scripts
(e.g. job runners which need to terminate stuck/old jobs forcefully)

Changes:

  - add 'safemode' argument to dj.kill

    Value defaults to Null which implies reading the value from current
    dj.config['safemode'] option, falling back to True if this is not present.

  - add safemode=False dj.kill operation mode

    This will apply the given restriction to the processlist query
    and kill all matching processes. Number of killed processes will
    be returned if no errors are encountered.
