Aria2 Integration troch jerrioboi

Features:
1. Replace Firefox's built-in download window directly, no need to click the download button in Firefox's built-in download window first or use the context menu to start a download.
2. It's able to send Headers (referrer, cookies) to Aria2
3. Run and Shutdown Aria2c Automatically.

Known Issues:
1. FTP download is not supported.
2. Sometimes you will get an error message after you click the download button probably because Aria2c doesn't start completely.
3. Mozilla doesn't allow us to send the referrer and cookies to the Firefox's built-in download manager.

=====================================================

You need to download and start Aria2 by yourself, complete at least 'Protocol,' 'Host,' 'Port' and 'Interface' in the options page and then click the 'Save' button.

If you don't want to start Aria2 manually, just write a program to start Aria2 in the background and register it to the system's 'autostart' or 'uri scheme.'
You can find the sample files here.
