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)
