1. Display somewhere the amount of diskspace left on the partition where the torrent default folder is.
2. Unrar option for torrents... It would be great for example if it would work for those scene releases, just detect the correct rar file (for example .part01.rar or .rar) and spawn a rar to unrar it - like on torrentflux. I would suggest disabling this option if more directories containing rar files are found... I guess it shouldn't be too hard to implement.
TBH i still use Torrentflux regulary just for these two things (especially to unrar stuff) - so this would be a great addition, and very useful for many i think

I am willing to do these things but i need just a little info.. I need to know how/where to write a function that can be called from the webui html file (like index.html from the classic skin)... An example would be nice. (i never coded in Python but i've been programming in C++/Pascal/Java for about 10 years)
