Too low contrast

[torgeirl]

Success Criteria 1.4.3 in WCAG 2 requires a minimum of color contrast. After upgrading Django (#102) and making encreased contrast default (#109) we need to make sure we provide a sufficient color contrast.

Some issues before addressing #102 and #109:

• Element has insufficient color contrast of 1.94 (foreground color: #ffffff, background color: #f0ad4e, font size: 12.0pt (16px), font weight: normal). Expected contrast ratio of 4.5:1 <a href="/authenticate/login/?next=/" class="btn btn-warning"> <span class="fa fa-sign-in"></span> Logg inn </a>
• Element has insufficient color contrast of 4.32 (foreground color: #777777, background color: #fbfbfb, font size: 12.0pt (16px), font weight: normal). Expected contrast ratio of 4.5:1 <p class="text-muted">Course name</p> (frontpage course headlines)

Fixed all the wcag issues i could find, the login view didn't use the wcag css styles at all, was missing a element inn its contex. But it is now fixed.

Had to change the opacity of .btn-primary.disabled to 1 instead of 0.65 and emulated the effect of lower opacity with a lighter color and had to set the text color to a near black color.

Fixed in 3.0.0b12.
