blog: clean up blog to allow usage with gcloud command

+ The app.yaml file needs to be in the same directory as the
  entry-point Go files, so those are moved from ./blog to ./
+ Go files within the context article did not have the +build OMIT
  directive, so gcloud would view them as files that needed to be
  built at deploy time. Add the +build OMIT directive and use
  the context package instead of x/net/context.
+ Switch to using a service instead of version and update app.yaml
  to account for this.
+ Use 1.9 as the runtime.
+ Remove superfluous .gitignore
