ENH: add context menu for deleting, ignoring, and getting help for cache entries.

ENH:  add delete cache button
ENH:  add information string above configure/generate buttons
ENH:  change search to search both columns, and from regex to plain string search
ENH:  add buddy info in cache entry view, so double clicking in the left column
      starts editing the associated value.
BUG:  fix file path editor so it goes away when focus is lost
