Still more KML and Google Earth

Some more updates and capabilities. I've added descriptions to the markers. If you click on any station marker in GE, a balloon pops up with:

• Name
• Country
• WMO number
• Rural/Town/Urban (also indicated by marker color)
• Airport (if true), Population, in 1000's (if given)
• Years over which data exists (may have gaps)
• Total years of data (excluding gaps)

You can also see this data by drilling down on a LH panel (long list).

I've also moved to using KMZ files, as is recommended. These are just zip files, each containing the appropriate KML file. GE will read them directly.

The docs repository file is still called KMLfiles.zip, and now includes the R code I used and a Readme.txt file.
