FS#10911 - Plugins: Fractals (formerly Mandelbrot)
- Rename the mandelbrot plugin to fractals
- Update manual accordingly
- Separate plugin's functionality into separate files
- Lay the ground for having fractals sets other than the Mandelbrot set.
For that the following will need to be implemented:
- Create a new file for the new fracral set
- Provide key mapping to switch between sets
