Extended support for Adventure Labs.

Hello, 
There seem to have been some changes in what the official API shows and what it is allowed to show. Cachly recently informed their users that they are showing all stages for non-sequential Adventure labs and the first step for sequential labs, could this be added in GCDroid too? 

I also noticed that the API seems to have an option to "exclude completed labs from the calling user", that would mean that when I include Adventure Labs in my search I wouldn't have to spend a bunch of time marking the completed ones as "fake-founds" any more, they just wouldn't show up on my maps. If possible I would like if this was added, could of course be a setting/option for those that like crowded maps. :)
