[Patch] Searching for non-existent usernames returns objects submitted by anonymous users

[avarab@…]

If I search for "user:THISUSERDOESNOTEXIST" in data that includes objects submitted by anonymous users (​example) JOSM will highlight the data submitted by the anonymous user.

Example XML for anonymous user data:

<node id="14581959" lat="64.0552442" lon="-21.9693467" version="1" changeset="99570" visible="true" timestamp="2006-08-31T20:18:45Z">
  <tag k="created_by" v="JOSM"/>
</node>

If the search engine is to support searching for anonymous user data it would be better to do so in a way that the data isn't returned when the user makes a type in a regular username. E.g. by searching for:

user:<anonymous>

or:

uid:0

Or something similar to that

The attached patch adds "user:anonymous" as a special search. And, searches for non-existent users will not return anything anymore.

This assumes that user 'anonymous' will not show up in real data. This user exists on the API server. However, since he has made no edits in over 2 years I believe it is very unlikely he will suddenly come back.
