Hey these are great changes

The update included in this request are fairly small. The biggest change is the inclusion of a second gsidiag_bin2txt directory, as older read_diag.f90 versions weren't directly replacable with the new (5.12+) versions. Also, I added some info to some of the readmes, made the webpage more complete, and whatever else. I think outside of some small config file changes, they are all in the subdirectories for the code I've written.  Additionally, some minor fixes and restructuring is added.

Let me know if there are any issues.
