Inconsistent filenaming in dist/

[mvl22]

A minor annoyance is that the filenaming in dist/ has inconsistent capitalisation.

Leaflet.fullscreen.js
Leaflet.fullscreen.min.js
leaflet.fullscreen.css

It would be good to normalise this in the next release - took me a while to realise this problem.

Other plugins I believe do use consistent naming: https://github.com/Leaflet/Leaflet.draw/tree/master/dist https://github.com/MrMufflon/Leaflet.Elevation/tree/master/dist
