Fix bug: correctly generate code when accessing external variables declared inside FBs as a structured variable (realvar := fb1.fb2.extvar1.realvar)


 Things that we must still check for in stage 3:

 1.a) "Any program organization unit attempts to modify the value of a variable that has been declared with the CONSTANT qualifier;"
 1.b) From table 16.a "The CONSTANT qualifier shall not be used in the declaration of function block instances as described in 2.5.2.1."
