[FR]: Support Multiple Link Types

[natefrisch01]

If one file were to have

tag1:: [[note]]
tag2:: [[note]]

we should display both, perhaps with a / between them

Ah! I feel like this is the next thing to tackle. If I want to have 3 lines connecting two nodes, I'll need to have the ability to do something like above (two different tags from one file).
