Corrupted glade files on merge from maint.

[Robert Fewell]

Hi,

While looking at some possible changes I noticed that three glade files in
unstable had been corrupted when they were updated from maint I think 14
days ago.

The merge from maint was this
<https://github.com/Gnucash/gnucash/commit/1895ae280c08eb6f750ceb546ad2af78c7a78bca#diff-5febfa05e8af4b218eb1ad2ac9b8dc4e>
and the maint commit was this
<https://github.com/Gnucash/gnucash/commit/c19f851c2958d6006a4d972ba320bf63ad8116d2#diff-11876f33cb16e39730ea67d9e550edc5>
I have corrected them by adding them to PR 235

Just thought I would point it out, have no idea why.

Regards,
Bob
