[TYPO3-english] Change default language flag in multi language site

[Albert Dekker]

I am building a site on the YAML basis. Yamle installs automatically the 
default language German and additional language in English.
I have changed the default to English however I can't get the eglish 
flag in the localization view.
I found something with
mod.SHARED.defaultLanguageLabel = english
mod.SHARED.defaultLanguageFlag = <filename to the language flag>

Still the lag stays the german one.

Even with a lot of searching I did not find any solution to this,

Regards,
