add targets to the gulpfile to simplify testing how various local specs display

(and modifying and looking again at those specs iteratively)

new gulp targets:
dev-dist: [lint, copy] (this runs the same code in dist, but without doing a clean first)
dev: [default, serve] (the task to run if you're iteratively making changes and don't want/need the dist directory to be regenerated every time)
