More attention box colours

[zarino]

We needed a .success class for attention-boxes in mapit.mysociety.org so I figured we should just add it to the docs theme so other sites can use it too.

While I was there, I split the existing red .warning style, into a red .error style and an orange .warning style. The warning/error distinction is more consistent with how other libraries like bootstrap do their alerts.

.danger also added as an alias for .error, for those with bootstrap muscle memory ;-)

Shouldn't warning be more orange than error/danger? ;)

Yeah – an orange alert for .warning would also be more consistent with how Bootstrap does it. But I left it as-is because other sites are already using the docs-theme .warning class and might be expecting it to stay red. @dracos Do you think I should just bite the bullet and change .warning to orange anyway?

OIC it was warning before. Well, if it's a reddy orange, I doubt anyone is precious enough to care :) It's used for the box on e.g. http://fixmystreet.org/customising/css/ , I think orange would be fine there too.

Yeah, it actually looks pretty good in orange:

Which would make the full selection:
