Fixed a bug where the default settings would not apply if you didn't first change the setting manually, making it so the media cache would not work.

If you had changed some settings from the defaults, you will have to set them again.

Also removed some redundant code, and legacy code used in a previous version making the extension even lighter!

Many updates have occured since the last version :
- Now the add-on is able to download from pages which have cookie verification (like cloudflare protected pages). It can grab the cookies from the media requests and replay them when downloading.
- The request cache no longer stores data from private browsing sessions, and is no longer trying to be accessed in private browsing sessions.
- Added support for more types of MPD files that can be downloaded
- Moved the download button to be the first one on the left, for easier access on mobile devices
- Added a credits button in the bottom app bar
- Fixed an issue where some MPD files would not be detected as such because of a typo I made
- Changed the flow of error reporting. Since it's apparently not allowed to share data in an add-on compatible with Firefox 39 and earlier (at least that's what I assume) now it has become harder to send diagnostic data but at least this should make the add-on available on the store again. If you were searching for the add-on and did not find it, that's why.

Enjoy the downloads!
