[CALC] Improvements and fixes for the numeric text output. CORE-8486

Browse Source 
- Fixed bug 12.37 13/06/2009 into multiprecision display (unicode only).
- Fixed bug when calculator was closed with statistics dialog open.
- Fixed bug in XrY operator.
- Fixed error into conversion unit.
- Do not append decimal separator if "ERROR" messages are printed.
- Remove call to _tcslen() and use return value of GetDlgItemText() where possible.
