Add option for autounmount
Even though filesystem notifications aren't implemented for FUSE, I decided to try my hand at implementing the autounmount feature (#128). I based it on the EncFS autounmount code, which records filesystem accesses and checks every X seconds whether it's idled long enough to unmount. I've tested the feature locally, but I haven't added any tests for this flag. I also haven't worked with Go before. So please let me know if there's anything that should be done differently. One particular concern: I worked from the assumption that the open files table is unique per-filesystem. If that's not true, I'll need to add an open file count and associated lock to the Filesystem type instead. https://github.com/rfjakob/gocryptfs/pull/265
