[GNC] export style sheet

[Nick Coe]

Hi,

I am using Gnucash 2.6.19 on a computer running Ubuntu 18.04 and am 
starting to transfer my files to a different computer running the same 
operating system.  I have the main file transferred OK so I can see all 
my transactions.

What I need help with is transferring an Invoice Style Sheet I created, 
as I can't seem to find where it lives.

Can you help with this?

Thanks,
Nick.
