CtextBox: Precise function getLines()

Browse Source 
Use refreshTextLineArray() for calculation of lines.
Note: 	count of lines will be only returned if CTextBox object
	is initialized with a valid CBox instance,
	otherwise count of 0 lines will be returned!

also remove inline declaration, not needed here
