G/T spreadsheet update (v1.12)

For those who may have used or want to use my G/T spreadsheet tool I have released an improved version 1.12.  This is not a bug fix.

An updated version of the spreadsheet GT.xlsm is at https://github.com/owenduffy/xl.

If Microsoft has frightened you off using spreadsheets with macros, you could use this with macros disabled, it just stops the green sort button working, all the cells still calculate properly.
