John Emmas e243d328a4 Fix a couple of issues when displaying the 'Preferences' dialog on Windows:-
1) When changing the 'Default folder for new sessions' we weren't responding to the appropriate signal (so the change wasn't getting saved in our user's 'config' file). We now respond to the 'selection-changed' signal.

2) If the above path happened to contain a tilde character we weren't interpreting it to mean the user's home folder. I've copied across a function called 'poor_mans_glob()' which Ardour uses elsewhere for dealing with this situation in other file dialogs.

Once we confirm that issue #2 is now working for all platforms, I'd suggest moving 'poor_mans_glob()' into libpbd. At the moment we have at least 3 definitions of it (all identical) scattered around in various places.

/** @file option_editor.h
* @brief Base class for option editing dialog boxes.
*
* Code to provided the basis for dialogs which allow the user to edit options
* from an ARDOUR::Configuration class.
*
* The idea is that we have an OptionEditor class which is the dialog box.
* This is essentially a GTK Notebook. OptionEditorComponent objects can
* then be added to the OptionEditor, and these components are arranged on
* the pages of the Notebook. There is also an OptionEditorComponent hierarchy
* here, providing things like boolean and combobox option components.
*
* It is intended that OptionEditor be subclassed to implement a particular
* options dialog.
