more services on gridviewer

There are now some more services on Grid-Viewer, and there are some visual tweaks.

Unfortunately, the data from multiple servers is not combining because of some back-end restrictions that I am going to work on next week, some additional refactors include separating polygons from pinpoints (thus, coastal states won't have really dark shadows (the result of multiple pinpoints being drawn in the same spot)), and storing data from multiple states in the markers (thus, flotplots should be able to distinguish which data came from which service in future versions).

Also, caching (with the help of Brian), fun Javascript and layout changes (with the help of Chris), and new multi-plotting and regional overlays.

Cheers everyone, have a good weekend!
