Update the print functions

[yubiuser]

What does this PR aim to accomplish?:

This PR serves multiple purposes.

1. It removes the CleanEcho and CleanPrintf functions. Both were introduced with Eliminate flashing by repainting rather than replacing #74. They solved the issue that after re-sizing the screen artifacts could remain. CleanPrintf did not serve any purpose, it was rather an intermediate state during this initial PR and was kept because it fitted the CleanEcho function well. The "cleaning" was done in the format string of the printf function with \e[0K already. CleanEcho was broken since Multiple Issues Fixed. PLEASE SEE COMMENT! #106, as the line needs clearing after the new output was written, not before.
2. It introduces the new ${clean_line} which does the same as the old \e[0K but with the (more generic) \e033[0K
3. It changes all CleanEcho to printf functions
4. It re-arranged the code blocks for the generation of the "Dashboards". So far, the code was organized by the information that should be displayed and then broken down by the screen size. Now we break down by screen size only. This has the big advantage that the code "displays" the final output in one place. One can now easily see what information are displayed for each screen size, without hopping between different functions. The code of PrintLogo() is now duplicated (once in this functions and once separated for each screen size) but this is a minor drawback.
5. Fixes PADD 3.8.0 display error with 3.5" PiTFT #251. With the addition of the interface and the model type, the number of lines increased and was (partially) greater then the "screen sizes".
