Fix diffusion browse queries in git

Summary:
If you try to load a directory in diffusion in a git repo that has a readme
file and you don't include a trailing slash in the path, you get an error
because we don't assemble the full paths of files correctly. This fixes that.

Test Plan: load such a directory in diffusion and see no fatal

Fix a redirect-on-login issue by allowing logged-out users to view 404 pages

Summary:
See T2102 and inline for discussion. This seems like the least-bad approach until we have something better.

The utility of next_uri seems much greater than the minor exposure of routable URIs.

Note that attackers can //not// detect if routable URIs are //valid// (e.g., "/D999" will always hit the login page whether it exists or not), just that they're routable. So you can only really tell if apps are installed or not.

Test Plan: Hit `/alsdknlkasnbla` while logged out, got 404 instead of login.

Add very basic scaffolding for Pholio

Summary:
I'm not going to land this until it's a bit more fleshed out since it would just confuse users, but this is probably more reviewable as a few diffs adding a couple features than one ULTRA-diff adding everything. Implement application basics for Pholio. This does more or less nothing, but adds storage, subscribe, flag, markup, indexing, query basics, PHIDs, handle loads, a couple of realy really basic controllers, etc.
Basic hierarchy is:

  - **Moleskine**: Top-level object like a Differential Revision, like "Ponder Feed Ideas".
  - **Image**: Each Moleskine has one or more images, like the unexpanded / expanded / mobile / empty states of feed.
  - **Transaction**: Comment or edit, like Maniphest. I generally want to move most apps to a transaction model so we can log edits.
  - **PixelComment**: Equivalent of an inline comment.

Test Plan: Created a fake object and viewed it.

Add basic transaction/timeline view

Summary:
This is still rough and not completely accurate to the mocks (and the mobile view is quite crude and mostly just "hey this technically works"), but I want to build Pholio on top of it rather than building it on something else and then swapping it out later and the API is reasonable enough.

This should probably be called `PhabricatorTransactionView` but we already have one of those. I might juggle the names in a future diff.
