Build using Bazel

This change integrates the Bazel build system into bio-rd.

We also add support for:
  - running go dep from vendored libraries
  - running goveralls from vendored libraries
  - running bazel-based coverage from travis

+Building
+========
+
+We use [Bazel](https://bazel.io) to build bio-rd.
+
+Build
+-----
+
+    bazel build //:bio-rd
+    bazel-bin/linux_amd64_stripped/bio-rd -arguments go -here
+
+or
+
+    bazel run //:bio-rd -- -arguments go -here
+
+Run Tests
+---------
+
+    bazel test //...
+
+
+Update Bazel BUILD files
+------------------------
+
+To regenerate BUILD files (for both the project and vendored libraries), you will need to run the following:
+
+    bazel run //:gazelle -- update
+
+Be sure to commit the changes.
+
+Update vendor/dependencies
+---------------------------
+
+After updating Gopkg.toml, run
+
+    bazel build //vendor/github.com/golang/dep/cmd/dep
+    bazel-bin/vendor/github.com/golang/dep/cmd/dep/linux_amd64_stripped/dep
+    # hack: dep of dep gives us these, and it breaks gazelle
+    rm -rf vendor/github.com/golang/dep/cmd/dep/testdata
+    rm -rf vendor/github.com/golang/dep/internal/fs/testdata/symlinks/dir-symlink
