Changeset 1fbf016a09 in tspsg for i18n/ru.ts

+ Added an ability to disable showing of the solution steps' matrices in solution output.

• Replaced Ok and Cancel buttons in SettingsDialog? with QButtonBox. Now the buttons conform the interface guidelines of the target platform.
• Increased the allowed maximum number of cities to 50. Solution steps' matrices aren't shown by default if the number of cities in task is more than 15.
• For WinCE the size of the toolbar buttons is now determined based on the device DPI instead of its resolution.
• Open and save file dialogs are now using native dialogs where supported.
• Reworked About dialog a little bit.
