There's a place, under BACKGROUND SETTING, where it says to use `xrandr --listmonitor` to determine how Xinerama monitor IDs map to screens etc. This should be `xrandr --listmonitors` with an 's' at the end.

Previously, the fact that --action interacts with --(un)loadable was only
mentioned in the documentation for --action, thus posing an elevated risk for
misunderstandings.

A signal interrupts the blocking function calls in the main iteration, so
there is really no need to do (unsafe) heavy lifting in the signal handler.

inotify_add_watch calls fail when the file is a url, since it does not
correspond to an actual on-disk path. The temporary file path fetched by
curl could be kept and monitored, but since this is unlikely to change
just avoid monitoring files opened via a url.

The default user agent is empty, which is not that friendly.

use libmagic to detect valid file formats

init_parse_options calls feh_prepare_filelist, which in turn calls
feh_file_info_preload if opt.preload is set. This function will load all
images in the filelist to determine their attributes, so we need to initialize
libmagic before calling init_parse_options.

Add a global `magic_t magic` and initialize it just once.

Also `feh_is_image()` now calls itself to check compressed files, saving
some duplicate code.
