Devices: Add a new RandomDevice :)
...
This new device uses the seeded Mersenne PRNG we use in the kernel.
This device is not meant for regular userspace use, but more for userspace to seed their own PRNGs from.
If the DeviceFS is mounted at /dev, this device can be found at /dev/random.

...
For now, we just have a version device. (this will allow us to get rid of sys_getversion!!)
More should be implemented soon.
