This class implements an upgrader that replaces the current executing copy
of YAAC with a newer version freshly downloaded from the distribution website.
It assumes it will run in a different JVM instance than YAAC was (launched by
Runtime.exec()) so that all files used by YAAC will be closed and therefore
deleteable and replaceable by the upgrader (for example, Microsoft Windows does
not allow deleting or overwriting a file that is currently in use by another
program). As such, the upgrader must be delivered in a JAR file separate from
YAAC.jar and all other JAR files used by YAAC. Furthermore, the upgrader cannot
install the upgrader file itself; YAAC needs to install the upgrader.jar on an
initial install and leave it alone for all future upgrades, or upgraded upgraders
have to be installed under a different path name, and moved into their correct
place after the upgraded YAAC is started the first time.
Note that this Upgrader is a Java Swing application, and therefore can only be used on Java Standard Edition platforms with a graphical UI (not on Android, for example). Currently, the only code that runs this program is in the Java Swing GUI code of YAAC proper, which guarantees that Swing support will be available.
