Virtual FTP for a WebSite. ( Not actually FTP )

Description: I originally made this program when I was running through a bunch of free webhosters. I got tired of relearning their interface so I made this one. I now have a 'real' website, and no longer need 'virtual' FTP. I couldn't bear to just dump it, so here it is. Now I'll probably have to make a bunch of versions ;) There is also an online web editor that I made to go with it... I'll add it in a few weeks when I get some spare time.
