mandos-monitor: avoid deprecation warnings from urwid
The urwid.FlowWidget class is deprecated. Replace it with inheriting from urwid.Widget, and setting the appropriate class attribute.
* mandos-monitor: Replace any mentions of urwid.FlowWidget with urwid.Widget. (MandosClientWidget): Inherit from "urwid.Widget" instead of "urwid.FlowWidget". Also, move MandosClientPropertyCache to first in inheritance list so that its __init__ method can absorb the "proxy_object" and "properties" keyword arguments. (MandosClientWidget._sizing): New class attribute; set to "frozenset(["flow"])".
(Thanks to an anonymous contributor for reporting this.)
