npm v3 should solve many of the issues around node_modules being in inconsistent state and shrinkwrap issues: changelog

v3 is still beta so we need test it well before jumping on, this bug is to track any issues that are found during the testing.

• the way we verify state of node_modules by copying over shrinkwrap.json as a fingerprint is not compatible with v3 and in fact it should be unnecessary - we should remove it from npm postinstall
• new dedupe algorithm changes paths to d.ts files for our tslint - the paths will neeed to be updated
• update travis.yaml
• update requiredNpmVersion in gulpfile.js
• update all dependencies and reshrinkwrap the dependency tree
• resolve issues with peerDependencies that now work differently in v3 (must be explicitly required by the parent component)
• benchmark difference in install time (using Travis)
