How to change default language tag in project html file?

When a new TMS WebCore project is created, the project html file always contains

<html lang="en">

Because of that, the language is set to english and when opening the web app in a browser with german language, it asks for automatic translation. So I have to change that in every new project to avoid this behaviour.

Can I change that default language? If not, I propose adding a default language entry for new projects in the TMS WebCore configuration.

Unfortunately the default language can currently only be changed manually in the project html file.

However this is a good suggestion and we'll consider adding a default language configuration option in a future version.
