[FIX] Pug always fails with 'failed to read gist.'

[Raptorox]

Every time I updated my system Pug would say 'failed to read gist.'
After I poked around the script a bit I found that it calls gist with a URL, but it only accepts gist id's.
As a workaround, I have added 2 variables,

GIST_NAT_SPLIT=$(echo $GIST_NAT | tr "/" " " | awk '{print $2}')
GIST_AUR_SPLIT=$(echo $GIST_AUR | tr "/" " " | awk '{print $2}')

and replaced GIST_NAT/GIST_AUR with GIST_NAT_SPLIT/GIST_AUR_SPLIT in the part of the code that reads the gists.
Would open a PR for this, but I have no idea how PR's work, so I'm opening this issue instead.

Created a PR, see #18.

In the meanwhile, I think you can just update the /etc/pug file to remove the username from the value and it should work.
