feat(commit): enable githook output streaming

We needed a way to provide incremental progress to the cli as the commit exec command runs. We
needed to land a PR in gulp-git first. This has now landed. This implements an incremental feedback
using the emitData option and does a few dependency updates.

Closes #8 Closes #28 Closes #31 Closes #32 Closes #33
