Limit storage usage plugin

[Zikushimo]

I would love a feature where you can limit the amount deluge can use in the default directory.

Exsample: i have a 2 TB drive where i want 1tb of torrents. So i go into the plugin's settings and type in 1024 GB into a value field and enable. Now all new torrents will be added as paused and wont allocate any space before other torrents have been removed.
