css: specificity, file loading

[karindalziel]

many css rules have things like td.classname or h1.classname. The element name shouldn't be necessary in most cases but in others it's causing specificity problems.

try to remove specificity issues, or at least identify where in core they are coming from and comment.

We'll probably have to remove element names from selectors in core too for selectors to override like we want. May have to check with others on how their theme CSS is written too.

In addition to other issues, I'm currently using !important to add link underlines which isn't great.

What I'd like to have happen:

• get django set up somewhat like rails, where you can specify that multiple files get loaded into one css file in a defined order. This has an advantage of being able to set variables in one file and use them in another
• if we do that, we'd have to override the bootstrap.min file from core so it isn't called twice (currently I'm overriding that by having it in the same location). I played around a bit with using blocks to do this, which would be fine
