Add link to Google Maps

[timtroendle]

I've added links to Google maps to the data table.

However, this is impacted by #66. I added some cleaning routines, but didn't manage to cover all issues of the "Location_coordinates" column. I suggest to not merge this before #66 is fixed.

This is a simplified version of #41 .

The table is now too broad. It works fine on larger screens, but on my tablet, it doesn't fit on the screen.

a) The map appears in the "map view" of google map instead of the sattelite view. ist there maybe the right keyword missing?
b) is there a way to strip "spaces" from the search term. It seems to fail, for the very first link because of spaces.

[timtroendle]

a) I did not find a way for that unfortunately. I think it's not possible.
b) I do remove whitespace, but this is non-breaking whitespace, see #66. Instead of trying to fix this here, I think we should rather fix the data.

[richard-thonig]

right.
a) yes. seems to be a problem with using search, vs explicitly pointing to a location
b) fixed it in the new version.

@timtroendle In the new version of the data I changed them to consistently use decimal point i.e -27.734,23.063
This should allow us to use the explicit formating and satelite as well as zoom parameters in the google-maps link?

[timtroendle]

I will look into it after #64 is merged.

@timtroendle in the website update PR, I saw that the first collumn seems to be broken:
maybe this can be fixed in this PR as well?

[timtroendle]

Did you rename the "name" field?

For reference: this is the descrption of Googles API:

@richard-thonig Can you review this again? With locations given in decimals now, this should work better than before.

[richard-thonig]

I think we should use the explicit version of the link. I gave it shot and it worked. Hurray!

[timtroendle]

Very nice. Looks great!
