Fix "context not available" in contextless diffs

Summary: D4351 swapped this from a map to a list, and then stopped it from getting to the ChangesetParser so it didn't make it to the Renderer.

Test Plan: Ran "arc diff", copy/pasted it into the web UI. Saw a diff with "context not available" blocks in between missing contexts.

Add the tokenizer.ondemand setting to Core for now.

to make it for one option, so stick this in core for now.

Make feed its own application

Summary:
Fixes the two-level nav issue introduced by D4376.

(My claim that this page is device ready in the code is something of a lie, but it's fairly close.)

(@chad, this could use an icon at some point, or you can point me at which one you want and I can take a stab at slicing it.)

Test Plan: Looked at feed; saw it not-broken. Also checked public feed (which should just merge at some point).

Simplify context parsing and add test coverage

Summary:
  - Remove 'missingNew', etc. It's impossible for a diff to popluate these, as far as I can tell (I can't generate such a diff, or find any which generate it).

Add font-size back to textareas.

Summary:
By default, users who enable monospaced textareas were getting 10px font sizes.
This is worse than the 12px non-monospace users saw which is what D4377 fixed.
This diff adds the font-size line back, but at the correct value of 13px instead
of the former 12.

Test Plan: Looked at a textarea in monospace and no longer saw 10px font.

Somewhat give Phriction the new Breadcrumb UI.

Okay, just a forewarning, this is horrible right now.

But I think it's an okay enough start that it's worth sending what I've done.

This rips out the old Phriction breadcrumb UI and replaces it with the new one
that other apps have been starting to use.

Allow displaying more users at once in Differential overview

I want to check the work of several people (bootcampers) at once.
This implements the OR filter required for that.
In the next diff, I plan to implement also the AND filter which can be useful too.

Searched for several people, clicked all filters.
Searched for one person, verified that pretty URL is still created.

Allow filtering Differential overviews by other participants

Summary:
This is useful for writing feedback - what did I work on with someone?
This creates `AND IN (...)` and not `AND AND AND` if more participants are specified.
User may not expect it but whatever, it works the same for the most common case of 1 extra participant.
It would be nice to have this also for other filters but it would by way harder.

Simplify hunk parsing

Summary:
Simplify whitespace-ignoring diffing:

  - Currently, we generate two diffs (one ignoring whitespace, one normal) and then copy the //text content// from the normal one to the whitespace-ignoring one.
  - Instead, copy the //change types// from the ignoring one to the normal one.
    - This is cheaper and much simpler.
    - It means that we have the right change types in reparseHunksForSpecialAttributes(), and can simplify some other things.

Simplify whitespace changes, unchanged files, and deleted file detections:

  - Currently, we do this inline with a bunch of other stuff, in the reparse step.
  - Instead, do it separately. This is simpler.

Simplify intraline whitespace handling:

  - Currently, this is a complicated mess that makes roughly zero sense.
  - Instead, do it in reparse in a straightforward way.

Partially fix handling of files changed only by changing whitespace.
Partially fix handling of unchanged files.

Test Plan:
  - Ran unit tests.
  - Created context-less diffs, verified they rendered reasonably.
  - Generated a diff with prefix whitespace, suffix whitespace, intraline whitespace, and non-whitespace changes. Verified changes rendered correctly in "ignore most" and "show all" modes.
  - Verified unchanged files and files with only whitspace changes render with the correct masks.
