Log Message:
x11/citron: update to 0.11.0

- Configuration: Added new date symbols.
- Configuration: The battery group, or whatever YAML calls it, now has a format
  option, similar to the date group. Its symbols are fully documented in the
  manpage, under the BATTERY SYMBOLS section.
- Network: When disconnected, the network notification will show a
  "network-wireless-disconnected-symbolic" icon. In other terms, the \ 
network
  notification is contextually-aware.
- Miscellaneous: Some refactoring work has gone into our formatters (which are
  responsible for the final format of the notification's body).
- Miscellaneous: Added a CHANGELOG.md that keeps track of the history of changes
  introduced by every version.
