Package versions are growing increasingly out of date

[kotfic]

Package	Local dependency	Current version
GDAL (python)	1.10.0	2.2.0
mapbox-vector-tile	0.5.0	1.2.0
Werkzeug	0.11.13	0.12.2

Note that mapbox-vector-tile is also forcing us to hold back protobuf to 3.1.0 because 0.5.0 is incompatible with newer version of protobuf.

Also, we're currently testing on python 3.4.3 on circle and would be better off testing against python 3.5 or 3.6.

Does this affect OpenGeoscience/geonotebook?
