Moved registering CSS functions from wpcm_fron-end.php to wp-course-manager.php
Added setting to save what pages are to be used to display the plugin content. This is needed to know what page to link to when linking between lecturers, courses and the schedule.
Added all content to the lecturer display in the front-end. What is left now is to link to the correct courses page, where course information will be displayed.
Added linking the courses from the lecturer page to the courses page, as set in the plugin options page. The link is only created if the option is set, otherwise only the unlinked course title is showed in the list.
Changed how the page checks if the form data is submitted, and the options should be saved.
