Installer: If next .SYSTEM file is not found, just QUIT.

Browse Source 
Previously, an error was shown. This means using QUIT.SYSTEM was
required if you wanted to launch Bitsy Bye (or whatever selector you
installed). This meant extra code, and wasn't user friendly. You may
still want QUIT.SYSTEM if you have e.g. BASIC.SYSTEM later in your
directory.

In addition, `QUIT.SYSTEM` is present which isn't a driver but which immediately invokes the QUIT handler (a.k.a. program selector).
In addition, `QUIT.SYSTEM` is present which isn't a driver but which immediately invokes the QUIT handler (a.k.a. program selector). This will happen automatically if the last driver can't find another `.SYSTEM` file, but `QUIT.SYSTEM` can be used to stop the chain.
There's also `PAUSE.SYSTEM` which just waits for a fraction of a second before invoking the next driver file. (Why? In case the log messages from the other installers goes by too fast!)

## How do you use these?
The intent is that you use a tool like Copy II Plus or [Apple II DeskTop](https://github.com/a2stuff/a2d) to copy and arrange the SYSTEM files on your boot disk as you see fit. An example boot disk image catalog that is used on multiple different hardware configurations might include:
