Export to EXCEL#235

I would love to just export all brew batch data from all historical brews and make statistsics and analysis in Excel.

I think this is a bad idea, instead it would be nice to be able to see statistics in the app itself and make the analysis there.

I think from an development perspective it is an easy fix to make an excel export. To develope and implement a statisic package is an totaly other story. And nothing says that one thing exclude the other! :).
