Plonetheme.barceloneta

- provide some spacing between event summary and content [vangheem]

- Fix extending barceloneta with xi:include [pbauer]

- fix in and out widget button style [vangheme]
- no one likes the star for required field label, try circle
[vangheem]
- add plone-loader style so you can add decent loader to javascript
[vangheem]
- add styles for search form [vangheem]
- Cleanup: Remove unused resources. [thet]
- Fix toggling navigation at mobile widths. [davisagli]
- Remove sticky footer (it required a hardcoded height, which does not
work for an element that may have varying content). [davisagli]
- Add clearfix to `.row`. [davisagli]
- pat-modal pattern has been renamed to pat-plone-modal [jcbrand]

- Add language selector widget [bloodbare]

- Change font family of `form.widgets.IRichText.text` textareas to
monospace. This affects the texteditor only in non-Richtext mode and
helps editing e.g. Restructured Text. [thet]
- Change `min-height` of textarea fields from auto to `4em`
(description, etc.), respectively `12em` for IRichText widgets (e.g.
when displayed without a visual editor). [thet]
- Return to being a clean Diazo theme so that we are a safe starting
point for people building their own themes and a good practice
example that works when copying the theme in the TTW theme editor.

- Remind committers to add changelog entries. I'm not your monkey.
