FLDigi fails to install

[mmirabent]

When trying to install FL Digi, the install script finds two versions and fails. I narrowed it down to this line in FLDIGI.bapp

FLTAR=$(curl -s https://www.w1hkj.org/files/fldigi/ | grep .tar.gz | sed 's/.*fldigi/fldigi/;s/.gz.*$/.gz/')

Right now that variable gets populated with two tar files

$ echo $FLTAR
fldigi-4.2.10.tar.gz
fldigi-4.2.11.tar.gz

I have submitted a PR with a possible fix here #194
