[FEATURE] Better discovery/browsing of Hackerspaces

[silent88]

Hi,

I discovered FIXME Hackerspace thanks to MyHackerspace, in 2015 I was awake at 2 AM and I was browsing the F-Droid app store, trying to get bored enough to sleep. I installed MyHackerspace and found that there was a hackerspace in my city, it was a completely random happenance.

Joining FIXME was a life changing experience and I wanted to highlight the browsing/discovery aspect of the application, to help other people like me discover hackerspaces.

I have two big features in mind:

1. In MyHackerspace to sort the hackerspace list by country.
2. To make a map with Google Maps which shows all the hackerspace in directory.json for whoever wants to see what is near them, or visit Hackerspaces when traveling.

https://github.com/silent88/MyHackerspace/commit/74721d820549ce6eb05ff4c12bdcdcf97e6f0a53
Here I marked the code to modify in order to have a sorted list.
Instead of loading the list with only the name of the hackerspace, you can load the list with "country code" + "" + "hackerspace name".
This is a related issue: Filter spaces

2:
In order to have create a Google Map we need a centralized repository of GeoData.
It does not make sense to have MyHackerspace query all hackerspaces dynamically only to build a map, or a simple UI list.

Discussion about modifying the centralized repository is happening here:

Regarding country mappings, also check out SpaceApi/schema#74. (Although for discovery a distance based solution might be better.)
