Rewrite in C - Githubissues

I've decided to rewrite Errands in C. Why? Performance. While writing python code I found myself optimizing things that shouldn't be optimized due to python's pretty slow nature. It's a good language for small or not complicated GTK apps, but for Errands it became a bottleneck. Especially when implementing search functionality. Memory usage and micro-freezes with large amounts of tasks played a big role too. C is much simpler language that has unmatched performance. All of the libraries is written in it. So it's going to be much better choice for this project.

All progress will be on rewrite-in-c branch.

Feel free to ask questions.

With my initial version in C it's showing very promising results:

Loading time is cut in half
Memory usage is cut by 60%
Overall performance improvements and snappiness
No micro-freezes
