Add option to hide the language selector (#1106)

* Added option to hide the language selector in the header
* Added `hide_language_selector` Switch to BasicsPage
* Added `hideLanguageSelector` property to ForumSerializer
* Apparently fixed the "Add Extension" button locale.... someone must not have compiled their changes :P

* Changed hideLanguageSelector (and such) to showLanguageSelector

* Change `core.admin.basics.show_language_selector_heading` to be `_label`

* Change showLanguageSelector in ForumSerializer to be boolean, default: true

* Ooops! Remove console.log 🤦‍♂️
