Added :
- Changed os.path to pathlib library to access files
- Radio buttons for alphabetical filtering in the search dataset window
- New connection interface
- More explicit Geo Columns buttons
- More explicit Metadata button
- In export, button "changed" -> "search" (to avoid confusion)
- All URI data sources (PostGIS, Oracle ...) layers are now saved as a .geojson
when exporting
- Added a searchbar for the tags in the search dataset window
Bug fixes :
Private datasets wouldn't show up even with an authenticated account
Layout for the dataset list in search dataset window displaying uncorrectly
after applying filters
Changing between "organizations" and "dataset" in the OpenData section would
sometimes cause an error
