mmdolze 77bf952dd2 Change icon handling and charmaps: 
* The full block icon now has index 0 and the heart has index 7. This makes
  the full block work if vBar custom chars are loaded (which use index 1-7).
* Prevent (hbar, vbar, bignum) modes from overwriting custom chars (except
  full block).
* Prevent the heartbeat from overwriting custom chars in vbar and bignum mode.
* Make the driver point to 0x1A and 0x1B characters for right/left arrow
  characters (those are the codes from HD44780 A02) and make all charmaps
  pointing to the correct characters.
* It is now possible to map the tilde character.
* Update other drivers that use hd44780-charmap.h (IOWarrior and ula200).
* Replace characters using charmaps on input instead of output!
* Remove some unnecessary comments.

/** \file server/drivers/hd44780-charmap.h
* Character mapping for HD44780 devices. Translates ISO 8859-1 to known
* HD44780 (and compatible) ROM character sets.
*
* \note All supported display controllers have their custom characters
* available as codes 0x00 (0) to 0x0F (15). Theses character codes
* MUST NOT be mapped.
* \note By convention drivers (hd44780, IOWarrior, ula200) use codes
* 0x1A (26) and 0x1B (27) to access left and right arrow characters.
* Map these to the corresponding characters of the controller CGROM.
