It's a Go import path, something we can 'go get'

Rob had a comment in #311 
"It seems like we may want to "go get" the provided import path for the user -- seems like a common case is not having it cloned yet. What do you think?"

as to the comment about "github.com/robfig/revel" import deletion
(said comment which I am unable to find on github)
...
is not actually a deletion, but a reordering of the imports into groups
so that the import statement looks something like:

import(
// Go standard library packages
_a_blank_line_
// Go third party packages
_a_blank_line_ 
// Application specific packages
)

with each group alpha sorted
