Make leaflet-map plugin work offline
As the plugin is using online tiles to display a nice background, it will not work offline. Some fixes might be used
- Embedding a full version of tiles set as a side project. Will be heavy, and implies many system tweaks
- Proposing a vector (geojson?) tiddler to add a minimal layer for locating the datas (countries boundaries? rivers? mountains? forest? biggest roads?...). Will also be (very)heavy, depending of reference scale.
not planned for now
