Adding a hardcoded banner to kalite landing page to announce hackathons ...

...this weekend. Temporary fix to what will eventually be database driven.


Changed: landingpage less to insert a bootstrap announcement at top of landing page. This is hardcoded and will need to be removed on Monday. 

Also, not sure if this was the right way to do it, but branched directly from master. @bcipolli @rtibbles @wangguan59
