Contrast on warning messages is not high enough and "Log in anyway" needs to be bold

[Kristina Hoeppner]

The color contrast on "alert-warning" is not high enough to pass WCAG 2.0.

Warnings can be seen, for example, when you masquerade as a user at the top of the screen and also when you created a new user and log in as them and you see the "Log in anyway" message.

The "log in anyway" text (just the link, not the rest of the text) needs to be bold as in previous version of Mahara. It's a regression that this is not the case anymore.

The screenshot is from the raw theme. All themes will need to be checked.

The alerts have a different calculation to statuses which was the one we checked for accessibility. Have now added overrides for alerts to inherit the same formula as statuses.

Links in alerts now bold.
