Fix bug when declaring data type directly derived from array type

Fix conversion of binary digits to hex, when generating code.

Fix missing '(' when declaring new simple derived data type.

Ignore underscores in decimal integer constants when determining size in bits...

When checking semantics of expressions, skip semantic checking of data type definitions
(not yet supported). If we don't skip, all subsequent POUs would not be checked.

Fixing algorithm that determines bit size of constants containing underscores.

Merging with Edouard's version

Fixing bug related to setting array variables with values coming from other variables
(e.g. X[0] := Y;)

Added __IEC_OUTPUT_FLAG, to mark variable whose forcing implies refresh on eache cycle.

Fix bug when debugging located variables of type memory (%M) for all variable classes

Removed dead code

Fixing implementation of CU, CD, and CUD in standard library.

Deleting dead code.
