Update meteor
Support asymptotic progress bar for constraint solver

Until we either can estimate progress or have a spinner...
Change the 'easy' instances of rawLog to use Console

Rationalizing logging is definitely a TODO
Fix typo
Minify then concatenate

This has insignificant cost in terms of final output size;
but it lets us yield and maybe do caching etc
Make 'meteor run' pretty
Print debug timings from enterJob, even if not in message capture
Fix some old_spacebars_test tests

… so that they test the right thing
Fix falsy helpers (like `0`)
Use Npm.require, not require, for uglify-js
Fix comment about deprecating _wrapAsync
Merge branch 'devel' of github.com:meteor/meteor into devel
Fix uglifyJs loading correctly this time
Remove stray debugging aid
Replace keepalives with a check if the parent pid is still running.

Downsides:
* Doesn't catch the case where the parent is CPU-hogging (but maybe we
  don't want to catch that case anyway, since the bundler not yielding
  is what's causing #2536).
* Could be fooled by pid re-use, i.e. if another process comes up and
  takes the parent process's place before the child process dies.

Untested so far because I haven't been able to actually kill a parent
process in such a way that the child stays alive.
Add test for runner process being SIGKILLed.
