Add VisitCallExpr to the AST visitor

When HandleTranslationUnit is called from the AST consumer
and the visitor function TraverseAST is called, the
VisitCallExpr function is automatically triggered

The translation functions are hold within CallExpression
that's why we visit them

The VisitCallExpr function
-checks that the CallExpression:
	-is within the input file we're interested in
	-contains a translation function (tr or qtIdTr or translation)
-retrieves and stores the translation information:
	-file name
	-line number of the translation function
	-context
	-source
	-comment
	-plural
	-id
