Problem: Delphi - No code is generated for global constants.

[stephan57160]

Solution: Generate missing code.

Additionnally, this fixes also global/class constant names when project name is like 'foo-bar-project' or 'Foo Bar Project'. In both cases, we now have:

• Global constants:

  // this is a
  // multi-line comment
  // for global constant
  FOO_BAR_PROJECT_GLOBAL_CONSTANT_STUFF = "123";

• Class constants:

  // multi-line comment
  // for class constant
  FOO_BAR_PROJECT_FOO_CLASS_CONSTANT_STUFF = 234;

Instead of invalid constant names...

Note: There might be many more issues to solve with such project names ...
