Fix Node 0.11.14 incompatibility

See https://github.com/floatdrop/gulp-watch/issues/98
travis :: add Node 0.11
merge :: 'patch-1' of https://github.com/UltCombo/node-stream-array into UltCombo-patch-1
merge :: 'UltCombo-patch-1' into devel
package.json :: updated concat-stream to ~1.4
test/0.js :: create test to denote result of [].shift()

As undefined is bad for ending object streams, its worthwhile tracking
it.
test/2.js :: create test to verify empty array
README.md :: monitor devDependencies
package.json :: v1.0.0-beta
