[Feature Request] Duplicated name and illegal characters check

[ONLYA]

Sometimes when I copy and paste the widget's name, I easily forget to add more letters to make it different, which causes the silent crash without any warnings when running. It took me about 30 minutes to find out the issue.

Illegal characters like () can cause problems when running.

I hope the duplicate name and illegal character checks can be added to the tool. Those will be quite useful for people to get away from some strange errors.

I'm afraid this is not easy to do.

wxFB can generate output for different languages and apparently these have different rules about identifiers. I remember someone was using chinese characters for generating Python output which was apparently legit but definately is not possible for C++.

Duplicate names are also difficult, depending on scope identical names might be allowed. Also, some components define a name attribute but don't use it in the generated code.
