Fixed #2
Fixed automated build script for pie charts

The build step to generate piechart data did not conform to the data
structure of the code statistic analysis tool.  This meant that every
framework was getting the default chart data.

Fixed #4
Updates download links and link generation scripts

iOS links are no longer include on page and download version dates are now
calculated correctly:

+ Calls to git now return a number
+ Latest commit per implementation AND FILE EXTENSION used to choose link
 + Previously the extension was ignored, so some links were ignored

Fixed #5
Standardised Automation scripts line endings

Line ending of post are a mix "\r\n" and "\n".  Choosen to standardise on
the latter.
