Example Code-Definition in main.dart increases binary size when using custom FA

[Drackrath]

Describe the bug
Using Custom FA, its required to modify the code and import the lib as an override. However:

• I want to add the FA-Code to a repository, so changes can be made on the fly
• The "example" and "test" code is useless overhead when not needed
• example code is in the util\lib\main.dart in which it doesn't belong
• util is needed to regenerate with the configurator.sh or .bat

To Reproduce

• clone the repo INSIDE a repo into smth like third_party
• delete "example" folder
• get an error

Expected behavior

• no error
• slim FA version?

Version:

• FA 10.12

Possible fix:

• Modify util\lib\main.dart to pass variables so example is only run on demand
• Modify the util\lib\main.dart to duplicate into \example, so \example is its own project and the configurator needs to be run inside there
• Decouple example from base-code completely
