Of course, it would be much more pleasing to the eye to have an icon to display. An alternative would be to fix the weather applet to display no icon instead of a broken one if no data is supplied for the current condition.

I used dptrs because I didn't want to break the internal API, which is public in a way. As more people use the backend changing things get more risky. the dptrs are for the member data vs functions. But, if we don't need the dptrs in the ions, we can get 'em out.

> The Ion makes use of wetter.com's officially-supported REST API. The API supports forecasts for up to three days, so the Ion does not supply any information about the current weather conditions. The forecast for the current day is split between night and day whereas the following two days are provided as an aggregated value for the whole day, respectively.

Profiled it for memory leaks using Valgrind, which did not bring up any leaks in the control of the Ion. Those two still look somewhat suspicious, so I'd like to get your opinion about them:
