Bundle JRE in AppImage

[probonopd]

An AppImage is supposed to have no dependencies apart from what can be expected to be present on every target system. Hence, JRE should be bundled inside the AppImage. See these recipes for examples.

Java Not Found...

The correct java version was not found on your system. Click on the button below to start downloading, or install it by typing the following command(s) in the terminal: 

sudo apt-get install openjdk-8-jre 

or (depending on your system): 

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

We're using electron-builder, so not sure how to change it so that a custom recipe can be added.

But anyway, that window you see essentially does the same thing as the recipe, if you don't do the commands (which I still prefer since the user will have an up-to-date java), then he can just click the download button which will have the same effect as packaging it (but without the increase in file size).
