This patch adds a benchmark tab to SysInfo!

Available tests & Implementation Status:
-------------------------------------------
Integer Arithmetic: done
Floating Point: done
Text Rendering: done
Gfx Rendering: done
RAM Performance: in progress
SD Performance: not yet done
CF Performance: not yet done
-------------------------------------------
I will complete this on weekend by adding the last
tests and adding a comparison table for known systems :)
Have Fun!
