0.3.1-beta

App changes

Tiled (TMX) export option: from the project settings (F1), check the Tiled export option to save Tiled compatible files along with the LEd JSON.
DISCLAIMER: this export is limited because Tiled doesn't support some core features from LEd, like different grid sizes in the same level or Array of properties in Entities. This export is only meant as a short-term solution to quickly load LEd data in a framework only supporting TMX files. See documentation for more informations.
Better active/inactive visual state for rules and groups of rules in auto-layers
Inactive rules are no longer exported in the JSON file
Pressing F key twice fits the current level in view but with less padding
Added an automated JSON format documentation generator (see JSON_DOC.md in sources)
Added version badges in the JSON doc to quickly identify changes per versions.
Updated home page
Updated sample maps
