Add a 'current' url for the nightly images

[kallisti5]

A current url for the night images would be super handy. I've needed one a few times in the past.

An example use case is an automated way to spawn a virtual machine with the latest nightly image.

Example:

http://haiku-files.org/unsupported-builds/x86-gcc4hybrid/current-raw
http://haiku-files.org/unsupported-builds/x86-gcc4hybrid/current-vmdk

Temporary(?) workaround:

  echo "Getting latest Haiku version..."
  wget -q http://www.haiku-files.org/unsupported-builds/x86-gcc4hybrid/ -O latest-haiku.html
  HAIKU_TAR_XZ=`perl -ne 'print if /VMDK/../raw\.tar\.xz/' ~/latest-haiku.html | perl -ne '/\.\/(.*raw\.tar\.xz)/;print $1'`
  rm latest-haiku.html
  echo $HAIKU_TAR_XZ
