pngbehave 6.x-1.5

- Changed settings page to use textareas for long selector lists #343681: CSS class/Selector input field is too short...

- Added new option for specific exclusion list

- Considerable reduction in the number of calls and variable references

- Moved the padding reducer for scaled images to AFTER the image is processed
This keeps images with padding > size from disappearing or throwing errors

- Padding calculations now correct for negative padding values

- Added

to pngbehave.module to force IE background image caching which speeds up tiled/repeated image corrections.
