Detects lines of code that have a semicolon (‎;‎) but not a statement

Justification: An empty statement can be a sign for missing code.

Note: There are good reasons for using empty statements. For example, in a CASE statement it can make sense to explicitly program out all cases, even those where there is nothing to do. When this kind of empty CASE statement contains a comment, Static Analysis does not generate an error message.

Importance: Low

CASE value OF
1:DoSomething();
2:;              
3:DoSomethingElse();
END_CASE

--> SA0003: Empty statements

CASE value OF
1:DoSomething();
2:;              //nothing to do
3:DoSomethingElse();
END_CASE

--> No SA error
