Crawler

This extension could be used to browse all images of a website recursively.
As technical limitation, we can't automatically download all images into your local file system. So we choose to provide a good UI for these images within browser. In its future version, we will add functions to export data into other formats.

Version 1.1 change list:
1. category the images we got by its domain
2. add URL input box so that user can change crawl site in the manager page.
3. performance enhancement --> use lazy loading so that the image will load only when you scroll to it.
