Update travis configuration (#228)

* Update travis config

 * Separate out individual build jobs for faster wall-clock testing

 * Fix clippy not actually denying warnings (excluded examples because
   these are currently failing and have non-trivial fixes)

 * Add build job that checks --no-default-features works

 * Add build job that checks for intra-doc-resolution failures (excluded
   tide because of bugs in re-exports with the intra-doc feature)

* Fix warnings

* Fix doc-link in tide-cookies
