Advanced Torrenting options.

While the torrent menu is on an episode, it can get quite big and being able to remove things that you don't use tidies it up.

Changes:
* Added 2 new settings to the settings page, Enable/Disable Streaming & Directory
* Added 2 new settings variables to the SettingServices.js
* Added code to the mini-torrent controller to check if button is enabled or note.
* Added padding to the top of the alert notifications in settings so they aren't right under the previous button.
* Updated bootstrap css to improve the button layout a bit.

Seeing as preview doesn't work, Bootstrap.min.css changes;
From:
``` CSS
...;margin-bottom:20px;...
```
To
``` CSS
...;margin-bottom:15px;...
```
