Adds Some Utilities For E621
The E621 Utils script is a simple utility that adds the 'Download', 'Download Page', and 'Get Link List' buttons so you can quickly download and get posts on E621.
On the top of the page, there will be the 'Download Page' button, clicking on it all the posts on the page will start to be downloaded. In each post there will also be a new 'Download' button clicking on it will download the single post. The 'Get Links(Source)' button will list all image sources and download them as a text file. The 'Get Links(Posts)' works like the 'Source' version of it but it makes a list of all posts.
The script uses the GM.xmlHttpRequest function to access the E621 content provider, so it needs to be enabled, otherwise only an HTML 'Download' button will appear, and no extra functionality.
The script is in the alpha phase, also I may add new functionality soon.
