Description

I have fixed the txtPrimary and txtSecondary classes to be on the correct text in the index view.
Along with this, since the old links used txtPrimary I have added a linkPrimary class which will represent the base link colour before any other effects take place.

The default ass colour scheme is still in place and works with this PR.

Recommended

For further additions to this theming, I would suggest adding a txtTertiary class which will represent the ad text colour. or the size text colour.
I did not include this though as that is on your discretion to add.
