Remove the comments settings for vim tab width and expansion variables.

Remove the comments settings for vim tab width and expansion variables.

These add unnecessary bloat for everyone to carry around, so we just
remove them now.

I'm trying to upload, but git cl upload does not like me it seems.

  File "/home/tfarina/depot_tools/git_cl.py", line 2342, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/home/tfarina/depot_tools/git_cl.py", line 2328, in main
    return dispatcher.execute(OptionParser(), argv)
  File "/home/tfarina/depot_tools/subcommand.py", line 245, in execute
    return command(parser, args[1:])
  File "/home/tfarina/depot_tools/git_cl.py", line 1607, in CMDupload
    ret = RietveldUpload(options, args, cl)
  File "/home/tfarina/depot_tools/git_cl.py", line 1487, in RietveldUpload
    issue, patchset = upload.RealMain(upload_args)
  File "/home/tfarina/depot_tools/third_party/upload.py", line 2680, in RealMain
    vcs.UploadBaseFiles(issue, rpc_server, patches, patchset, options, files)
  File "/home/tfarina/depot_tools/third_party/upload.py", line 1215, in
UploadBaseFiles
    print t.get(timeout=60)
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 528, in get
    raise self._value
urllib2.URLError: <urlopen error [Errno -2] Name or service not known>

That seems to always happen when there are "many" files.
