Closing braces together on new line in arrays and array unions

[kdauer]

Problem to solve

As Squeak Developer, I want C-style braces whenever a block or array is used as receiver so that the closing brace is on a new line.

Further details

In old versions of the C language, argument types needed to be declared on the subsequent line (i.e., just after the header of the function):

/* Original pre-ISO C style without function prototypes */
int main(argc, argv)
    int   argc;
    char  *argv[];
{
    ...
}

So this is the standard we will use
relates to #21
Examples would be:

^ {
    'a' -> 'b'.
    'b' -> 'c'
  }, {
   self urlOfTweak -> 'tweak'
  }

[
  a squared.
  b yourself
] on: Error do: []

as long as it is not configurable this will remain very subjective.

Acceptance Criteria

• After writing and poppy printing code receiving Blocks (and only receiving Blocks) are formatted in C-Style (see examples)
