System agnostic logo replacement script

[AlexWinder]

The logo-replacement.sh script installs openjdk-11-jdk and imagemagick natively on the host if they don't exist.

tak-server/scripts/logo-replacement.sh

Lines 8 to 20 in 2d9c769

	jar 2>/dev/null
	if [ $? -ne 0 ];
	then
	sudo apt-get install openjdk-11-jdk -y
	fi
	convert >/dev/null
	if [ $? -ne 0 ];
	then
	sudo apt-get install imagemagick -y
	fi

A better solution would be to have a Docker container to handle the replacement. This would make the script completely independent of the host operating system.

Meh. Too much effort for a pic of a banana.
