Add min/max size as configuration option for input format

I made a small change to the flickr_filter.module @ D6 so that the commentary on the Flickr linker input format configuration page is more in line with what you see on a node/add/* 'page' .

< return t('Insert photos or photosets from Flickr without tags: [flickr-photo:id=230452326]');
---
> return t('Allows you to Insert Flickr images: [flickr-photo:id=230452326,size=s] or [flickr-photoset:id=72157594262419167,size=m]');

Ill get this change committed to the development branch later this week .

Best, Paul
