Dynamic update, improved UI & inital localization

[julianrichen]

After my initial PR I wondered if I could make the plugin automatically get the streams validity & quality from livestreamer. Apparently you can! A lot of the code has been changed and I apologize for that, if it is to much of a change and you don't like the direction I'll make another repo and call it something different.

Here is a video of the redesign: https://vid.me/v6xZ (never used vid.me before, hopefully it works)

Changelog

• Used the default install location of livestreamer as a first attempt
  • If it fails to find livestreamer it notifies the user to use the preferences tab
  • Default locations are:
  • Linux: /usr/bin/livestreamer (works Debian linux)
  • Windows: C:\\Program Files (x86)\\Livestreamer\\livestreamer.exe (works Win7)
  • Mac: /Applications/livestreamer.app (Can't verify)
• URL validation (regex) is now done with livestreamer; no need to create our own list Closes #7
• Stream resolutions/quality is returned from livestreamer and updated in the drop down
  • Attempts to organize the qualities based of a preset but not always correct
• Redesign interface
  • Only 1 panel used, status is updated with panel.port.emit("status", "<message>");
  • New status for each step of the process
  • Loading icon (gif) to inform the user of the current status panel.port.emit("loading", true);
• Improved ContextMenu support
• Inital localization support in locale/ (en-US)

What I tried (and failed):

22; I could not for the life of me figure that out. It might be a limitation with nsiProccess

Next plan:

17, want to get livestreamer working in the browser with a click of a button. Seamless integration as if it's the player.

Wow! This is what I initially wanted to do, figure out a way that livestreamer tells us if the url is valid or not. I will see through the changes and merge them asap. Huge thanks!

edit: for #22 it might be possible to use with the new child_process api. This API was not available when I created the addon.
