Got file open working
:e now uses the current directory
Simpler IVimHost initialization

Create a single hook which just passes IVim to IVimHost instead of many
hooks which pass individual values down
Easy method for active IStatusUtil
Removed the HostResult type

If the host wants to raise an error message it should just raise the
message directly.  No reason to indirect through this type
Directory contents loading
Directory contents formatted properly
Tagging of directories works

Unfortunately though I really need to use a classifier here and not a
normal tagger.  The foreground customization doesn't affect text in a
tagger, just the box drawn around the text.  Need a classifier here.
Changed to classification
Changed to EditorUtils2010
Directory classification working

Finally got the directory names to show up as green
Directory navigation
Fixed a focus issue
Fix the suites
Change the title
