MediaInterface.kt: fix MediaWiki API call to retrieve thumbnail URLs properly

Browse source 
Before this change, the API calls to MediaWiki would request thumbnails with atleast a specific width,
rather than height. These thumbnails would often be extremely low resolution on very wide images,
such as panoramas.

This change instead requests thumbnails with atleast a specific height. Panorama thumbnails are now
at a higher resolution than before. Additionally, the height parameter is now represented as an
integer which can be changed more easily.
