add & expand targets

Sorted alphabetically (was hard check before adding)
changed:
* `logo.*` gif, svg, etc
* grunt/gulpfile`.*` .coffee, .ls (LiveScript), etc
* add `LICENSE`, `*LICENSE.*`, `doc/` (perhaps questionable, but who runs these via CLI or in-app?

Note: I think occasionally READMEs are read; IIRC atom editor uses them directly.

Thanks for your project!
