Customizability of the overall site style #33
Description
Since this system is not technically a DSV system as much as it is a SPIDER system, the general style of the site needs to be customizable to follow SPIDER's look and feel (which may change over time).
This can be a fairly technical feature, one approach would be to allow administrators to upload a custom css file that overrides the built-in styling.
#31 is kind of a prerequisite for this, in that it needs to be realistically possible to override the core styles of the site in a way that isn't totally overwhelming. Things like the colors the site uses should be set once and reused instead of being declared on each item. Similarly with text sizes, logos, button styles etc.
