Support for clipboard between Qt and Symbian applications

Clipboard now supports copying text between Qt and Symbian applications.
Text is always copied to QClipboard and to Symbian clipboard. If
QClipboard is empty, Symbian clipboard is checked and text is pasted
from there. Corresponding test cases added.
