Put movie pictures in a fixed sub folder (/pictures) of the movie dir.
This eliminates the need for the config options "moviePics" and
"aliasMoviePics" and is somewhat similar to the behaviour for tv series.
Move "getFolders" to API/Util and generalize it.
Fetch categories from API instead of using hard coded values in the
front end.
Add hidden windows system folders to ignore list.
Replace hard coded categories in index.php with functions in the
controller classes.
Let the ShowController control the database updates. Also replace
hardcoded categories with actually looking up the folders on disk.
Pretty print json files.
Generalize category determination, which now considers the host name.
