- Add open folder dialog support (FILE_DIALOG_OPEN_FOLDER mode) for CefBrowserHost::RunFileDialog (issue #1030).

- Standardize file dialog behavior across all platforms (issue #1492).
-- Show a file type filter list on OS X.
-- Show the file extensions as part of the filter list description on all platforms (e.g. "Image Types (*.png;*.gif;*.jpg)").
-- Rename the CefBrowserHost::RunFileDialog |accept_types| argument to |accept_filters| and expand support for filters that will be displayed as-is in addition to the currently supported mime-type and extension-based filters. For example, a filter value of "Supported Image Types|.png;.gif;.jpg" will display "Supported Image Types (*.png;*.gif;*.jpg)" in the filter drop-down list and accept *.png, *.gif and *.jpg files.
-- Persist the selected filter item index by passing a new |selected_accept_filter| argument to CefBrowserHost::RunFileDialog and returning the newly selected index via the CefRunFileDialogCallback and CefFileDialogCallback callbacks.
-- Rename the CefBrowserHost::RunFileDialog |default_file_name| argument to |default_file_path| and use the directory component, if any, to set the default directory location. If |default_file_path| ends in a trailing path separator it will be treated as a directory without a file name component.
-- Add FILE_DIALOG_OVERWRITEPROMPT_FLAG and FILE_DIALOG_HIDEREADONLY_FLAG values to cef_file_dialog_mode_t for controlling those behaviors where possible.
