Changing Datatable Highlighting and Text Color

[sandertyu]

The goal here is to change the datatable styling so that when cells are selected, the background color does not change and the text color does not change. Currently on live, the background color becomes a whitish-pink, and the text-color changes to match the unselected grey background color, making the text nearly illegible. My changes here remove the background color changes entirely. The selected cell looks like this;

This pull request will be good to merge once the text color changes are fixed. Alternatively, we can keep the background color changes when selected. However, the font color is still difficult to read except when hovering over a selected cell. The full issue is available here at #68

@sandertyu Is this ready to be merged? I forgot about this.

Sorry, I saw the email and then forgot to comment. This is not ready to be merged. The current state of this PR is exactly as the image shows; I've removed background highlighting, but the text is unreadable when you select a cell. To be ready to merge, the text color needs to be changed when selected. I detailed the exact CSS to do that in issue #68 , but when I actually implemented it in the CSS file, it did not work.
