[Xastir] Idea for re-org of map directories

[Øyvind Hanssen]

Ive tried modifying Xastir such that it can decide to display maps or not, 
depending on the current zoom level. My approach is to allow a per-
directory file which specify the maximum zoom level for the maps in 
this directory. This seems to be sufficient since what I need is just to 
stop displaying of maps when they are scaled down below a certain 
threshold. Maps that are too much scaled up are simply overlayed by 
other maps (if the directories are named in the right order). 

In my implementation each file entry in the in-memory index is 
given a new field, which contains the zoom-level threshold. 
It is then straightforward to allow an extra keyword in each 
geo file as well.  

It seems to work well for me and my maps. I can post my changes if you 
are interested.
