Apply syntax highlighting to Exprs in REPL
As discussed on slack a while ago, it's now near trivial to make inspecting large Exprs much more pleasant with JuliaSyntax highlighting.
See the commit message for more details.

If anyone's up for it, I think this should be a pretty quick and easy review & merge :slightly_smiling_face:
@fredrikekre / @KristofferC any thoughts on the current version of the code?
The current version seems ok to me at least. Does it still obey --color=no?
Yep, since it's just printing via. StyledStrings now, and StyledStrings respects the colour property as expected.
Bump @KristofferC / @fredrikekre
This looks really simple and straight-forward to me, I hope it can be merged soon -- it's been ready (at least from my POV) for over 2 months
