1. Switch to our own CDN to download built-in maps.
2. Install path of map data was revised for provider's name space. (original: /oruxmaps/mapfiles/Taiwan, now: /oruxmaps/mapfiles/Mapsforge-Taiwan) The new install path will take effect upon installing new map or updating original map.
3. If map was installed at new path, originally installed maps will be listed after re-install app.
4. Fix possible cause of some crashes in previous version.
5. Improve some permission prompts.
