Make DATE command output compatible.
JIRA issue: CORE-13848
- Add STRING_DATE_NOW resource string for
localizing "The current date is: ".
- Output by ConOutResPuts function.
ConInString() should display a newline when it encounters the terminating
carriage-return pressed by the user for ending string output.
+ Remove the extra \n hacks in FilePromptYN[A].
Improve outputted strings from DATE and TIME commands.
+ Rename some STRING_***_ERROR defines.
