Improvements to dialog boxes.

- Allow the spacebar to work like ENTER when a button has focus.
- Improve textbox behavior: allow selection, delete selection, replace selection when typing.
- Preselect textbox contents if it's preset when dialog is invoked (Save as, Find and Change dialogs)

- Fix: an asterisk sign will be only added to the valid searchable characters in a listbox if the user is explicitly searching for it.
