Title: Get character using charAt for IE7 compatibility

Using the additional 2 libraries allows for latest version of proj4js to work in IE7:

+ https://github.com/es-shims/es5-shim (for the Array.map functions)
+ http://bestiejs.github.io/json3/ (for the missing JSON function)

However there remains one error in IE7 caused by using the bracket notation to access a character rather than the charAt function which is supported by all browsers. This single change allows proj4js to run in IE7 (as far as I have tested it).

See http://stackoverflow.com/questions/5943726/string-charatx-or-stringx for more details.
