Code generator: Group statement: to be able to solve IF and FOR_EACH (and similar)

[coderbloke]

No need for dedicated IF and FOR_EACH (and similar) tag
In generator specification it can be defined, if a tag behaves as block statement
Closing tag can be provided there also.

For example

_IF_USE_EXT_LIN_
...
_END_

... nicely can live together with a ...

_FOR_EACH_ACTION_
...
_END_

... if the _END_ tags are defined per CodeGeneratorAction

CodeGeneratorActions:

1. tag: _IF_USE_EXT_LIN_
   tag_type: IF
   close_tag: _END_
   action_method: _is_ext_lib_used
2. tag: _FOR_EACH_ACTION_
   tag_type: FOR_EACH
   close_tag: _END_
   action_method: _get_actions

Such handle functions are no returning String as code substitution, but rather

• bool fo IF
• Array for FOR_EACH
