Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work.

Give the emulator testing environments 128 MB of RAM. I'm working on porting GCC and it needs a fair bit of memory to run.

Build: Remove grub from default build process This removes grub and all the loopback device business from the default build process. Running grub takes about a second, and it turns out it's inconsistently packaged in different distributions, which has led to at least one confusing issue so far (grub-install vs grub2-install). Removing it from the basic path will make it easier for people to try Serenity out. There are now two scripts that can be used to build a disk image: 1. `build-image-grub.sh` - this will build an image suitable for writing to the IDE hard drive of a physical machine, complete with a partition table and bootloader. This can be run in qemu with the `qgrub` target for the `run` script. 2. `build-image-qemu.sh` - this is a simpler script which creates a bare filesystem image rather than a full MBR disk. Both of these call out to `build-root-filesystem.sh` to do most of the work setting up... the root filesystem. For completeness' sake, I've retained the `sync.sh` script as a simple forwarding to `build-image-qemu.sh`. This relies on the functionality from #194 and #195. #195 allows us to use `/dev/hda` as the root device when nothing else is specified, and #194 works around a strange feature of qemu that appends a space to the kernel command line.

More work on IPv4 sockets and /bin/ping. It's now actually possible to ping other hosts on the network! :^) I've switched the "run" script over to starting QEMU with user networking since that works better for my testing needs right now.
