xonotic autobuild downloader: add the base scripts

+Windows users:
+Double click update-xonotic.bat and wait for the download to complete.
+
+Linux/OSX users:
+Change to this directory in a terminal, then run ./update-xonotic.sh and wait
+for the download to complete.
+
+Redoing this step at a later time will only download the changes since last
+time. Note that any changes inside the Xonotic directory will be overwritten.
+Do your changes in the directory that has the config.cfg file!
+
+Secret trick: if you create a directory Xonotic-low in this directory before
+running the updater (or later, if you rename the Xonotic directory the updater
+created to Xonotic-low), this script will download the low version of Xonotic.
+If you create a directory Xonotic-high in this directory before running the
+updater (or later, if you rename the Xonotic directory the updater created to
+Xonotic-high), it will download the HQ version! If none of the two exists, it
+will download regular Xonotic. Only one version of the game can be managed by
+this script.
