Some items can't get translated

[artam]

I briefly started to update the language translation and found out that there are some controls the translation has no effect on them:

- buttons in Playlist - [WID20] 106,..,110

and for some of the settings their IDs don't exist in the lng file:

- all that stuff in Preferences -> Equalizer (Frequency bands..., Center frequency..., Equalizer enabled, buttons Add, Change, Delete Default - moreover, these buttons aren't active at all... is it an intend? :?:

BTW, a longer time I noticed that in the BSPlayer install packages you don't include the latest translations from people that did post them here. There are still lng files of old versions included. Why?
