global search improvements
Submitted by Christian Hergert
Global Search could use a revamp now that other moving parts are starting to land.
typing a filesystem path like /usr/include/ should start autocompleting files underneath making things integrate well here is where we really make this thing shine, it could be our "killer feature"
typing a function should show you the docs inline in the search result, just like auto-completion.
"devhelp/" should show devhelp directory in the results area, including the files in the directory.
find-other-file should use the global search bar (with other similarly named, or suffixed files) in the list
