Update localizations for FileDialog.

- Separate some of localization resource keys for cases of hotkeyed string:
  - `fdOpen` -> `fdOpen` and `btnOpen`
  - `fdSave` -> `fdSave` and `btnSave`
  - `fdSaveAs` -> `fdSaveAs` and `btnSaveAs`
- Modify or add resource keys for general purpose:
  - `fdNo` -> `btnNo`
  - `fdYes` -> `btnYes`
  - +`btnCancel`
  - +`btnOk`
- Extract the procedure of build default title to `GetDefaultTitle ()` for FileDialog.
