Fix a couple of docs typos

[smoh]

Just removing typos. I removed docs/build directory from git tree as well.

Please remove the

else
    # Otherwise upload package to dev channel
    anaconda -t ${ANACONDA_TOKEN} upload -u intake --label dev --force `conda build --output ./conda`

branch from .tavis.yaml to get the tests to pass.
