Minor fix to plugin title

The wrong title was showing in the Plugins UI screen ("Segmentedbed" instead of "Segmented Bed") due to a bad entry in init.py. Fixed.

Less hacky code

Merged PR1 from @larrrox which improved my comments with more detail, and added a much cleaner way to loop thru the array using the reorderMatrix.

Thanks @larrrox !

Better layout with a nicer color scheme

A more well-behaved CSS/HTML layout.

77% less crappy code

This is far less of a hack and slash job now. There is still some "magic" array manipulation to reorder the tiles that, frankly, a better coder will likely laugh at. That's on the to-do list.

Initial release - Prusa XL only

This is the first release. It's admittedly a bit hacky in the code structure, but it is well-behaved and should not cause any issues.

At the moment, this is designed for the output format for the Prusa XL.
