Added script to publish API docs up to github pages

Script requires: 

* The two added files
* Appledoc installed 
* Ant tool (available via mac ports)
* gh-pages branch created - you can do this via github console or just create and push a branch called gh-pages

Then run: ant

. . . reports are pushed up to gh-pages. . .. edit your README to link to the reports. . . (Example in my fork). 

This script can be called by a build server like Bamboo or Jenkins to publish latest docs after every build. . . .
