Add Component Ecosystem to Dependencies Table

### Current Behavior:

It's not obvious (at least to me), what type of component each one is. And by type, I don't mean what #449 is referring to (application, library, framework, device, etc.), but I mean programming language each is written in.

### Proposed Behavior:

Add a column that indicates the language for each. e.g., Java, .NET, Node.js, JavaScript, etc. Maybe do this at the same time as (or before?) #449 CHANGE: changing this to ecosystem (e.g. maven, nuget, hex, pypi, etc) per Steve's comment below.
