Changed the html layout in WPCM_show_one_course(), to put the dates above the lecturers.
Added CSS to float the dates to the right, except when shown on devices with less than 600px width.
Started using NetBeans IDE, which automatically added a row to .gitignore.
Netbeans project properties for the project.
Added links to more_info_urls when showing the dates for a specific course.
The link is only added, if the more_info_url field is not empty.
Also added "SORT BY date, city" in the SQL to fetch the dates for a specific course (in wpcm_db_access.php).
Small changes in the Plugin options page.
