Added new collage layout

[KH404]

Hi everybody,

it took me a while but now I found some time to implement a second collage layout as desribed in issue "New Collage Layout #164"

Therefore I did the following changes:
• added a new checkbox in lib/configsetup.inc.php with the following options: '2x2' and'2x4'
• added the default layout in config/config.inc.php ('2x2', the currently existing layout)
• changed the code of lib/collage.php so the layout parameter is input value of a switch/case statement.
The case '2x2' is the old existing code of the collage. Everything in case '2x4' I added.

I tested the code on my raspberry pi 4B and it worked well.

Hope the code is good enough to be pulled. Php is totally new for me. I normally work with C and Python ;)

Hey and thanks for your contribution.
I guess by accident, you've deleted some options which needs to be reverted.

Another solution which I need to improve can be found here andi34#108

Hi,

I changed the files lib/configsetup.inc.php and config/config.inc.php so the options which where deleted by accident are in the files again.

Thanks a lot!
I've applied some of your changes to the implementation I've been working on.
