Add linkouts for general sources throughout dashboard

If it is already there, I might have missed it. Just for convenience....

I'm guessing you were referring to linking to the main RePORTER page as a general reference, and not showing links for each individual project?

Taking this further, I suppose it would be nice to have general references for all data sources/services we use, i.e. iCite, Entrez, etc. on the dashboard. Changing the issue title and marking it as a low priority issue we can do later.
