Refactor / reorganization of molecule display functions

[janash]

The functions used for displaying molecule images using CDK are currently defined in two places. These should be defined in a module, and imported to the components where they are used rather than being defined twice (showSVG, hideSVG, etc). newSearch, loadMore, etc also seem to fit this.

dynamicGrid is also an example of a component that could be reused. It seems to be very similar between the two pages it is used, with perhaps the only difference being the display of the distance (this could be controlled with a conditional)

I think we can incorporate the showSVG and hideSVG functions inside the general graph functional component!
