Add more maps handlers

[lazerwalker]

I'd like to include everything supported in https://github.com/citymapper/CMMapLauncher

• Citymapper
• Navigon
• The Transit App
• Waze
• Yandex Navigator

Citymapper is the highest priority.

I have created #76 with citymapper, waze and some other improvements
