@Rico, this adds the version file back into the SDK w/o removing the revision
file. Once pub and the editor are reading from version instead of revision, we
can remove that file.

@rnystrom - you'll want to take a look as well.

Is there any chance we can make the version file match the semantic versioning
format pub uses (http://semver.org)? It seems confusing to have the version that
"dart --version" prints out be different from the version that users specify in
their pubspecs.

I agree re: consistency but it's not a change for this CL. The vm. editor,
dartium, and (now) the SDK all pull their version from the tool/version.dart
script (and the tools/VERSION file). I'd open a separate email thread w/ the
proposed change to the format.

It's not clear from this UI - these 5 lines were indented by 4 spaces, not 2.
pylint complained; I think the indentation is correct now but I can revert this
ws change if you like.

I changed this to be more consistent w/ that other open/write/close section.
