[weekly report] Week 8: Local map rendering in libchamplain

[Simon Wenner <simon wenner gmail com>]

Hi,

I finished the network-map-data-source. I added proper network error
handling and the ability to use a proxy server. The main features of my
project are now in place, so I optimized some code parts and removed
public functions, which aren't that useful anymore after the recent changes.
I also resumed work on libmemphis. The rule-set class needs to be
extended, so rules can be queried and changed. This task is still in
progress and it should be finished after this week.
