Updated README with new TODOs.
Updated to latest kernel image.
Clarified "sf write" command:

Not everybody's acquainted with extended shell syntax, where ${var}
means $var means "the value of var".  So, provide an example of the
expanded command, without any "$".
Added unbricking instructions.
Updated weekly_template.
Fix /etc/fstab linking.
Tried to make the README more self-evident.
Kernel version abstracted.
Turned kernel version information into environment variables.
Abstracted kernel version information.

Also, fail on errors, except for handled, known-bad commands.

Why're we allowing failures in some commands?  They'll never work,
because they depend on the actual DreamPlug hardware, but we can't
boot the built image on the actual hardware unless these commands run.
So, cheat: run them as far as they'll go, because that's just far
enough.
Don't repeat options from fbx-base.conf.
Restore original compression, it makes no difference.
Updated gitignore.
Reliable Maximum Image Size

"2G" cards vary in size.  Make an image of 1900M to suit the cheaters.
Clean Cards on DistClean

If distclean is supposed to clean an entire distribution, it should
clean the SD-card distribution too.
Standardize Build Target Names

All the fake (timestamp) targets are prefixed with "stamp".

"Stomp" was the other proposed naming scheme, but was ultimately
rejected by a committee that just doesn't understand what fun is.
Rootfs Properly Requires Predepend

rootfs-* requires stamp-predepend.  Act like it.
Automatically Build Torrents

Build torrents as part of the weekly image.
Indent TODO

Indent TODO a bit more readably.
ExMachina Dependencies

Add ExMachina's dependencies and sort package list.
