[GNC] Finance::Quote and TMX.pm

[Ken Farley]

Yeah I just messed about a bit with my install of GnuCash (v4.12) and 
Toronto Stock Exchange is grayed out.

I looked at the module and the only thing I changed was that there was a 
reference to TSX.pm in the header. I changed it to TMX.pm, then ran the 
quoting update script provided with GnuCash (gnc-fq-update), and now 
"tmx" shows up in the "Unknown" listing.

No matter what I do, the Toronto Exchange entry in the "normal" quote 
source list stays greyed out. I don't know what quote source (i.e. what 
is its name) that one is looking for.
