Fix getList arrOpt filter, news content lang keys; bump to 2.0.4
- Models: count($arrOpt = []) always reset the option array to empty, so getList() ignored every passed filter; use count($arrOpt). - news_content view: use core lang keys (admin.cancel/reset/update/submit/active/inactive/no_records) instead of the non-existent admin.core.* keys. - Bump plugin version 2.0.3 -> 2.0.4.
