+ Moved WatchList.cs to specific directory (just a matter of ordering)
+ Mark some properties and methods in watchlist as obsolete
+ Create Comparer class that are used for sorting (Only domain and
address atm, other a still stored with linq). Unlike OrderBy in LINQ, it
doesn't create a new list for sorting (so it saves memory), furthermore,
it runs faster.
Finally, change to type of Watch.Address from nullable lon to regular
long (the rare times watch.Address.Value was used, there wasn't any
check of null and so, program would have crashed -
InvalidOperationException -)
