Calc Guide updating to 3.5

Hi All

I have started updating chapter 14 Customising Calc to version 3.5. It will most likely be weeks before it is ready for review but at least it is a start.

You might ask why this one? I am customising a copy of Calc to use for the other guides and finding issues with it as I go and learning how the guides are produced at the same time.

As Jean Weber said in another email "A quick-and-dirty update of the Calc Guide to LO v3.4 would be useful." I would say VERY useful!
