[MetaCRS] Proj4js license

[Michael Adair]

Hi All,

An issue over the Proj4js license was raised on the OpenLayers mailing 
list, basically someone can't use it because of the LGPL license.  I'm 
not sure why that license was chosen but it probably came as a 
carry-over from the MapBuilder project.  The intention for has always 
been for there to be no restrictions on using the library, so I'm 
proposing changing the Proj4js license to use the MIT license.

Comments?
