Layers for markers, pokemons on top (#222)

* - Check permissions to set my location
- Change scanning location marker to a smaller one
- Center pokemon markers
- Add pokemon markers to a hashmap to keep track of all the previous scans
- Update marker snipper with current expiration, added a update markers method
- Call the update markers on resume and after scanning

* Show how many new pokemon where found after the latest scan.

* - Moved PokemonMarkerExtended to map package.

* Removed hack for negative expiration. Assuming that a -1 expiration means that the pokemon is expired and will be removed in the new update.

* Change the calls to the to get the range search to MainActivity and let the events and threads do the job of getting multiple steps at a time.

* Remove conflicted name class LatLng and add MapHelper to have the distance and translatePoint methods static.

* Remove extra loop in Niamtic Manager

* Make hex weaker.

* Fix niantic manager to prevent double call to range search.

* Show pokestops

* Add lured pokestops.

* Use show scanned locations and pokestops to show them or not.

* Add Clear Map menu item. Close suggestion on first search.

* Hide password in settings

* Layers for scanned locations, pokestops, gyms and pokemons.
