image_resize_filter 6.x-1.7

This release of Image Resize Filter makes some back-end changes to functionality. Most notably the behavior has changed on images that are not resized.

- If resizing remote images, Image Resize Filter goes ahead and saves all remote images locally regardless of if it needs to be resized.
- Width and height attributes of the original image size are now added to all images if they don't have any.

It also fixes several bugs regarding private files, improved efficiency (half the number of external requests if resizing external images), and several other efficiency improvements and bug fixes.

New Features:
#620108: Download all remote images locally (a hotlinking solution)
#765194: Always add height and width attributes even when not resizing

#698506: Setting border width causes image to resize as that width
#734024: Images with filenames containing '+' (plus) don't scale

#764912: Make Image Resize Filter work without allow_url_fopen

#764860: Including the same image multiple times at different sizes replaces the first image tag
