Big thanks to CreeperMario who ported this to HBL and made it available for use by other developers! <3
CreeperMario said in the comment on his pull request:
The keyboard can now be opened by calling launchKeyboard(&returnedString); (with char returnedString[256] above it). Once the user presses HOME, the string is returned and can be re-printed to the screen using OSScreenPutFontEx.
Most importantly, any user can easily insert the keyboard into their HBL program by copying draw.c, draw.h, keyboard.c and keyboard.h to their own project.
