Also always store android_bundle in the warehouse, because right now we download
it every time the meteor-tool changes (even if the android_bundle version didn't
change). It is still not ideal, as it will download a new binary every time you
switch between meteor-tool versions pointing at different android_bundle
versions.
.meteor/packages in new apps now contains "standard-app-packages", which implies
the standard set of packages like mongo-livedata. There is no special-casing in
initFromAppDir. This line has been added to all the examples, etc.
There's a new concept of "upgraders". "meteor run-upgrader app-packages" will
add standard-app-packages to the app, as well as all of the package in the app's
packages/ directory (an unrelated change since 0.6.4). This will be integrated
soon with "meteor update"; run-upgrader is essentially for testing.
project.add_package no longer adds packages that are already there.
