We want to ensure that when someone creates a button that the default style for that button is the secondary style - this is so that we don't end up with lots of plugins showing primary buttons everywhere.
If someone wants a primary button they should be adding .btn-primary to the classes.
- .btn, .btn-default, no class should be the secondary style
- .btn-primary should be the only way to make a button or anchor primary
- default anchor style should just be a link
- Update blueocean-plugin to reflect the class changes
