url editor doesn't handle namespaces with "dots"

[mikepizzo]

repro:

1) launch http://rapid.rocks/api-designer 2) paste the following into the RSDL Editor pane:

namespace my.Namespace
type A{}
service{As : A[]}

Result: SwaggerUi, CSDL, OpenAPI, and visual editor panes all display correctly, but the urlEditor gives no intellisense

Change the first line to myNamespace, and urlEditor works fine.
