Update README and bump version to 0.0.10

Since I'm about to release this version, update the README to mention
that I've tested it against beta 2 but not beta 1, but that the changes
in this release are not expected to cause problems with beta 1.

bump version to v0.0.9; last-minute README update

The README update is to try to update my estimated time for a beta1->beta2
update to something which might be more realistic, maybe, I hope.

v0.0.8: Try harder to find payloads directory

If micropatcher.sh fails to find the payloads directory, it's probably
because the PWD isn't the directory that contains micropatcher.sh. So,
it will now try to figure out its own directory, change to that, and
check again for the payloads directory.

This should fix a patcher failure that is happening in the real world.
That justifies releasing v0.0.8 with just this fix.

v0.0.7: add --force to kmutil invocations

A quick point release with just one change. Based on kmutil behavior I
observed during further patcher development, I believe adding --force
should make kmutil's behavior more predictable and more robust.

bump version to 0.0.6

bump version to 0.0.5

Finish up the v0.0.4 release

I've updated the README to correspond with this release's new behavior,
and I've bumped the version number to 0.0.4.

At this point, once you have the patched USB in hand, the process of
doing the basic installation is really the same as on a supported Mac,
except that you have to open Terminal, run one shell script, and close
Terminal again before running the Installer.

Bump version to 0.0.3

The big improvement in this release is that there is no longer any need
to reboot between set-vars and run-installer. I expect that v0.0.4 will
make it obsolete in an hour or two, but the release is done so there's no
real point in holding it back.

bump version to 0.0.2
