Better map data loading

[DavidLemayian]

A way to load less data to the map on initial check. Possibly only the geo points. Titles + category will be loaded via an ajax API call.

Steps to achieve this:

• Load only geo points with project ids.
• Load title + category badge on pop-up.
• Load categories with related project ids. (Possibly asynchronously when filter is fired?)

Things to watch out for:

1. More calls to the server.
2. Asynchronous category filter will need to initiate the "Loading map" screen.
3. Shareable link when category filter is an option, needs to be considered.
