lok: Allow whitelisting languages that should be used by LibreOfficeKit.
LOK may get way too many languages if there are dictionaries for them
installed which blows the pre-init to >2G easily; let's allow limiting that.
Also make the preloading of languages work with the internal spell checking
dictionaries and thesauri.
