[Balloon] latest bootloader in svn

I imported the current nick/daveB bootldr version into SVN last night.
it's a branch in
svn+shh://balloonboard.org/home/balloon/svn/balloon2/branches/

That should be exactly the same as what is currently in the balloon3
testv0.1 release dir (but it was very late and my first svn branch so
I may have screwed it up).

I've also fettled the permissions so everyone in group balloon should
have r/w access to the repo.

Can someone (Nick?) check that out and see if it builds/works OK for
you? If so then everyone can now work in proper versionned land for
future bootloader work and we should be able to get to the bottom of
the differences between that and the 'mainline' bootldr 3.0 in
svn+shh://balloonboard.org/home/balloon/svn/balloon2/trunk/bootldr

(I will also be changing the svn structure around at some point. I
don't think the
balloon2
trunk
bootldr
bbl
kernel
branches
...
balloon3
trunk
...
branches
...

structure is working out. there is more comonality than that (which is
good). So I propose binning the top layer so we have
trunk
bootldr
kernel
bbl
etc
branches
bootldr
kernel

etc.

It could be done the other way up (with trunk/branch split below each
app/program) but a) that's more change) and b) this gets the pesky
trunk/branch bit slightly more 'out of the way in normal use, I think.

If anyone has strong opinions state them now, as we don't wnat to
rearrange things any more than necessary in the future.

Wookey
