The original code would not work properly for a number like 1001 (with at least two consecutive zeros); the whole remaining number needs to be tested when deciding whether the zero needs to be replaced with the padding character.

yeah, went through a number of iterations, the current code should work properly, but please take a look at it.

Description
Adds functions to convert an unsigned int to a char array. Useful for OLEDs and displays, especially on AVR, as things like sprintf take up ~1.5kB of firmware space.
And instead of continually adding the same block of code, add a function into core to do this.
