Inspection - check if module namespace prefix is same as module file name

[arnostv]

Add inspection which checks if module name space prefix is based on module file name.

For example in module with namespace URI my://sample/namespace/myFirstModule.xq namespace prefix should be myModuleOne.

module namespace myFirstModule = "my://sample/namespace/myFirstModule.xq";

declare function myFirstModule:someFunction() {
  fn:true()
};

This inspection should be optional and not enabled by default.
