Allow for simple Popup too

[ocefpaf]

@Conengmo this used to be default but now it fails silently. This PR just add it back while keep the option for the more advanced GeoJsonPopup.

I should fix those tests... but this PR is good to merge!

I can take a look at those test. Hold on... I also need to fix the versioning thing :-(

[ocefpaf]

@Conengmo I did not fix any test yet but I separated them to make it easier to examine and make a decision.
I'll work on the version number next.

[ocefpaf]

@Conengmo are you OK merging this as is for now? I'll take a look at the version issue next and then the selenium failure. But I'm clueless on the latest branca failure there.

Could you split the changes to the tests/releasing into a separate PR? That will make it easier to track what changes we made over time.
