Hmm, why does the webui depend on both of these?

[Tim Song, 2015/04/14 06:00:12]

I want to also add UI to make CryptAuth calls, like GetMyDevices, which is very
useful for debugging the server state.

[Ilya Sherman, 2015/04/14 21:47:53]

Let's add deps as they become relevant, rather than trying to add all the likely
candidates upfront.

[Tim Song, 2015/04/14 23:24:05]

Done.

We'll need to create a DEPS file for the webui subdirectory, right?

[Tim Song, 2015/04/14 06:00:12]

Sorry, forgot to add the DEPS file.
