Added/updates ski maps for Trois Vallées (in February) and for Portes du Soleil (Champery, Avoriaz, Les Crosets, Morzine).

The area of Morzine, Les Gets is still only partial and needs further work.

Added some more slopes/lifts from memory (marked with source "local knowledge").

From my stay in Flims/Laax, I added slopes, lifts and restaurants based on the GPS tracking done while snowboarding.

It's yet not complete, some items are missing.
