Provide a means by which the tips of the day file can be translated.
I think these are best served as a simple text file, otherwise the key would just be tip1, tip2 etc. I definitely agree that these are not lst files in their current form, so I think the file name extension should be changed to txt.
I like the idea of a separate file for each language e.g. "tips_fr.txt". To avoid having to implement a new language processing module, we could add a new il8n key Tips_File_Name to indicate the appropriate tips file to use for this language. Then the tips could be loaded from that file if present rather than the default.
