Add translation module and lang switcher
- uses ngx-translate - extracts all strings marked with " XXX | translate " or <X translate> using ngx-translate-extract (npm run extract) - custom translation loader prevents empty strings - default language is english - will try to use the browsers language, will fallback to english - functional language switching menu - not compatible with current PO files - current JSON-translation can be re-used
