also, default-intel-detail and show-more-portals plugins fixed - the logic has been moved into IITC core, with the plugins just setting flags to change behaviour
- iitc now defaults to lower detail than the standard intel site when zoomed out - it loads much faster, shows more than enough for general use, and is less likely to trigger 'excessive requests' issues
- show more portals plugin: updated for interface changes
- show-less-portals-zoomed-out: deleted (this is now the IITC default)
- new plugin: default-intel-detail - restores the original IITC behaviour on zoom to portal detail level mapping. not recommended
