The standard app packages are brought in explicitly now.

.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.
Also include awssum update
"meteor list": completely ignore internal packages
templating implies spark and meteor: generated code needs them.

also finish getting rid of deprecated startup package, and some other minor
packaging cleanups to templating.
Forgot to include standard-app-packages/.gitignore.
Merge branch 'upgraders' into devel
Remove function moved from server file to common file.
