Merge branch 'fix/ci-lint' into 'master'

Make CI Lint form synchronous

This removes `remote: true` from CI Lint form, making it synchronous
form. This also removes some complexity related to displaying lint
messages.

View also has been updated, removed deprecated Bootstrap 2 tags.
Improved design.
