commit 73974f7397414b0931b80729ea716387f3c6a130

Fix JavaScript part of the tiles invalidation.
Now it is possible to type in in some cases, but for the full functionality,
tuning together with the server is necessary.

Don't actually create the tiles until after we get them from the server.
When a tile is requested, don't create anything yet, just send the request.
Create the tile after we actually get it from the server.
This is in preparation for the cancellation of the tiles requests.
