Add <!--IMAGE-LINK--> keyword for templates about llgal HOT 2 OPEN

Sure, that's easy to add, so why not?
Regarding documentation, you just need to add it to llgal.1 (likely right before ).
If you can write the code, test it, and submit a PR, that'd be great.

There was a little alert "Use of uninitialized value in substitution iterator" so I modified the previous code and also introduce two keywords instead of one, SCALE-IMAGE-LINK and FULL-IMAGE-LINK as is:

$line =~ s/<!--SCALED-IMAGE-LINK-->/$entry->{scaled_url}/g if defined $entry->{scaled_url};
$line =~ s/<!--FULL-IMAGE-LINK-->/$entry->{url}/g if defined $entry->{url};

I'll modify llgal.1 dans make a pull request if you agree with this proposition.
