Using brace initialization here causes bar.hpp to not compile when
included on its own, forcing all clients to also include
tray_manager.hpp and so on, which defeats the purpose of forward
declaring those classes.
This also allows us to remove the tray_manager.hpp, renderer.hpp and
parser.hpp includes from the clients of bar.hpp
Only updating when an mpd event occurred would cause issues when mpd was
playing and the machine was put to sleep because the elapsed time was
calculated by taking the time difference of the last update and now
which would give you wrong numbers, if the machine was in standby in
between.
Since the update function on the module is only called once a second (or
when an event happens), we can just update the data every time without a
huge performance hit.
Fixes#915
Breaking Changes:
* Date module no longer supports non-padded specifiers (i.e. `%-d`) and potentially other specifiers, see #792
- Check http://en.cppreference.com/w/cpp/io/manip/put_time to see supported specifiers
* Setting background color to `background-0` with gradients (refer to https://github.com/jaagr/polybar/wiki/Known-Issues)
