Make Sidekiq Web UI RTL-friendly (#3381)

* Unminify rickshaw graph CSS so we can maintain it

* Initial BiDi support for the Web UI

BiDi means the web app can serve both LTR and RTL languages at the same time.

1. Bootstrap-RTL overrides Bootstrap 3.3 styles for RTL clients
2. Application CSS was preprocessed thru rtlcss and then hand-trimmed to contain only RTL-specific directives.
3. Dashboard was tweaked to hardcode LTR for footer and polling gadget

* Vendor bootstrap-rtl.css

* Various RTL style fixes, need to flip all pull-* elements

* Upgrade Rickshaw to latest, remove dupe CSS

* Add Arabic language (credit to Milena Novakova)
Add Hebrew placeholder
Added dir attribute to html tag

* changes

* Clean up HTTP header generation, add Content-Language response header

* Use correct locale for hebrew

   USR1 will continue to be supported in Sidekiq 5.x for backwards
   compatibility and will be removed in Sidekiq 6.x. [#3302]
+* The Web UI is now bi-directional - it can render either LTR

 * Rails 3.2 is no longer supported.
 * Ruby 2.0 and Ruby 2.1 are no longer supported. Ruby 2.2.2+ is required.
