monitor-manager: Store logical monitors in a GList

Browse Source 
Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using
indices, put it in a GList, and use GList iterators when iterating and
alternative API where array indices were previously used.

This allows for more liberty regarding the type of the logical monitor.
