[Therion] convert excel to therion

[Tarquin Wilton-Jones]

Step 1 would be to get the data out of Excel and into a text-based
format. Axel suggests copy & paste, which works very well.
Alternatively, in Excel, use "Save as" to save it as a CSV file. Then
open the CSV file in a text editor that has a find-&-replace function,
and replace all commas with spaces. Save the file as something.th

It's entirely up to you which approach you would prefer.

Step 2 is to add in the basic Therion wrapper that Axel suggested.
