Feature 27: Selection of Points

[daniel-va]

Depends on #6. Resolves #27 Allows study points on the map to be clicked in order to select the asset that they belong to.

These are just some things i found when testing the aplication, before looking at any of the code (also, I am only revieweing this PR, not the one this depends on):

• Remove the openLAyer map controls
• The map does no longer zoom to the search results upon completing a search
• selecting assets on the map from the search results no longer works (this occured at some point, but no i cannot reproduce it, so it probably does work)
• not part of your PR, but when resetting a polygon from the search (without a search term), an empty saerch gets triggered
