fs.find complete, i think? fs.open, disk management done.

Here's what i got so far. I've been focusing mostly on creating the fs.open functions. So far i've got read, append and write. They should work in theory, but i haven't tested any of it so there's probably some bugs. I also added automatic disk parition management. Have a look and see what you can glean from it, cause i was kinda lazy comment wise :P Now im headed to bed though, i'll do some testing when i have time tomorrow.

Edit, some more small changes, and it works! I've only done the bare minimum of testing, but it's possible to create a vf folder, then use fs.open to open a file in it and write and read to it like normal. all i've had time to test.
