rather warn than barf on duplicate members due to config options name-clashing with target class members
When the super class constructor supports a config parameter, also let the generated subclass do so.
fixes JOO-64
In static code, instance members incorrectly hide static identifiers
http://jangaroo.myjetbrains.com/youtrack/issue/JOO-64

If an identifier is found in non-static scope, simply continue in
parent scope instead of throwing an error immediately.
However, the error message was not so bad, so if we could
restore this error message when it is actually justified...
Merge branch 'jangaroo-1'
Merge branch 'master' into jangaroo-3

expected result of new test for JOO-64 has to be converted into Joo-3 format to make test green
