Bump more dependencies

- jasmine_node became a multitask
- expect changed its main file name

Not updating:
- q 2.0 is marked 'experimental' on github
- jasmine-node 2 is still beta (gemnasium shows this wrongly as stable)
- connect 3 doesn't support node 0.8
- lodash 2 changed `_.after` which we call in `test-server`, and probably this breaks our test suite. Looks like we have some timing issue there which needs more investigation...
