BEFORE	AFTER

Added an option "Hide goal names"
Goal names (see, for example, a grey box with "right.left" written on them) are immensely helpful during some types of proofs, for example when we do induction proofs about functions.
In some proofs, however, goal names just clutter the interface, and it should be possible to hide them.
From now on, we hide the goal names by default, in the spirit of making the initial interface perfectly intelligible to the Paperproof novice.

Added an option "Always green hypotheses"
Again - this is to ease beginner's understanding of Paperproof proofs. Additional colors do ease the reading of a proof, but might be confusing initially. From now on, we let people turn on this functionality when they are ready for it.

Made it possible to render Paperproof in github codespaces

Just go to github.com/codespaces/new/Paper-Proof/paperproof and wait for a few minutes for your codespace to load.
That usually takes 2-4 minutes.
If you have a Lean repo, and you would like to enable codespaces in it, all it takes is these two files: .devcontainer.
If you would like to enable Paperproof in your codespaces, just add "extensions": ["[email protected]", "paperproof.paperproof"] (note that we fix the leanprover.lean4 extension version - this makes sure leanprover.lean4 extension updates don't break your codespace).

Here is what it will look like:

Changed the way initial hypotheses are displayed
Previously we had a fake init tactic. Now, we changed it to "HYPOTHESES" header.

BEFORE NOW
Changed the font and variable colors
Here we both move towards and away from Lean's default InfoView.
We changed our font to match the one Lean's InfoView uses - it renders mathematics symbols much more clearly than our previous font.
On the other hand, we changed the variable color from the orange color (used in Lean's InfoView) to dark pink, which is easier to read on our green node backgrounds.
