feat(gulp): add support for gulp tasks

[dmccaffery]

Condo should detect gulpfile.* files within the project and automatically execute gulp tasks with the following names:

• - ci
• - build
• - condo

In order to do this, the following must be true:

• - detect gulpfile.*
• - detect npm
• - use npm to install gulp (if defined in package.json -- we will not install manually)
• - use the local gulp install to list available gulp tasks
• - execute one of the following gulp tasks, in ascending order of priority:
  • - condo
  • - ci
  • - build

If multiple matching supported gulp tasks exist, execute only one of them based on the the first match from the list above in order.

Closing as gulp has been largely deprecated by the web community. Will revisit later if requested.
