properly handle ^C in console
use number instead of serial to pick devices in ui (faster start-up)
version 0.8.99.5
dropped activate_on_single_click, requires gtk 3.8
suggest appindicator library in solaar package
version 0.8.99.6
optionally listen for upower suspend/resume events to stop/start all receiver listeners
disable poll ticking

It was necessary to periodically check if the peripherals are still
online -- suspend/resume may cause Solaar to (wrongfully) remember the
status of devices after a resume.

Now that is handled by the optional upower module -- the hard way -- by
restarting all listeners on resume.
some extra asserts on hid++ 1.0 register r/w
properly handle tree re-selection when removing a receiver
don't use proxies for receiver/device objects

they should be unnecessary now that their status is properly tracked
initial support for performance mx leds

The leds light up when we get updates about the battery level.
Right now they are not (programatically) turned off.
fixed reading correct device kind on link notification
if the battery level is approximative, show a string instead of percentage
brought solaar-cli in sync with the latest gui code
minor clean-ups and formatting
replaced solaar png icons with svgs
some clean-ups in descriptors
recommend python-dbus and upower in debian package control
