Somehow, the fix in the previous commit didn't work, it seems that
sometimes epoll() doesn't trigger, even if there is more data in
sys.stdin. I'm sure I'm doing something horribly wrong here.
Anyhow, as a quick fix, check for the open bracket to be sure to not
buffer the first event too long.
Re-enable the possibility to define custom mouse actions by binding
commands to "<alias|module>.<left-click|right-click|...>". These
commands are then executed as shell commands.

Instead of having a thread that runs in the background continuously,
spawn a new one for every update interval. That speeds up the tests
quite a lot.

Show RTT measured by ICMP echo request/replies for a given host.
For that to work correctly, change the "full_text" callback for a widget
so that the widget itself is also passed as argument in the callback
method. That actually makes a lot of sense, since the widget can now be
used as a repository of state information.
see #23
Quite a lot of modules use the "if higher X -> critical, if higher Y ->
warning" idiom now, so extracted that into a common function for reuse.
see #23
Until now, as soon as a widget registered *any* callback, the default
callbacks (e.g. scroll up/down to go to next/previous workspace) didn't
work anymore, as there was a better match for the general registration
(even though not for the button).
To fix this, merge the callback registration into a flat registration,
where a key is calculated from the ID of the registrar and the
registered button.

If the computer runs on AC, display that instead of showing "100%" in
the status.
Also, if reading the charging status fails for some reason (except the
computer being on AC), go into critical state and display "n/a".
see #23
Allow modules to define aliases. This replaces the symlink mechanism
that was in place previously, because it was a bit ugly (and confused
code climate).
see #23
Make input thread non-blocking by using select(). This increases the CPU
utilization a bit (depending on the timeout), but makes the thread exit
cleanly, even if an exception is thrown in the main thread.
see #23
If a widget exists for an interface that is not there anymore (i.e. a
tunnel interface that has been removed, or a USB device that has been
unplugged), remove that widget from the list.
see #23
Re-add the NIC module with all its functionality (hopefully...).
This introduces a new concept: Instead of having separate queries for
critical and warning (which really are just another set of states), a
module can now return a list of states for each widget. All the state
information is then merged together into a single theme. So, for
instance, the NIC module can return a state saying "critical -
wlan-down", which applies the theme information for both "critical" and
"wlan-down".
see #23
I cannot get the min_width property to work right now, so in order to
fix the width of the CPU widget, pad the utilization to 3 digits (so
that even 100% aligns nicely).
see #23
The cpu module now has cpu.warning and cpu.critical thresholds. If the
CPU utilization is higher than any of those values, the widget's state
changes to warning or critical, respectively.
see #23
