<title> tag should only have wp_title()

cleaning the title tag, moving the conditional to function and modify
wp_title through filter
moving register_sidebar to its own function and hooking it to widget)init
Moving add_editor_style to after_setup_theme callback

as ZGani suggested, add_editor_style shouldn’t be used in init
callback. It should be placed in after_setup_theme callback
at page template, post title should be #located in the header

+ one page template, opus_posted_on displays “edited time” instead of
“published time” to show the relevancy of the page
Correct margin-left for list items
