							##### New characters in fonts #####
	==============================================================================
	[..] Use font_tmore.c and add line to corresponding font like font_t54c
			 Don't forget to adjust the length of the font in the last line starting
			 const tFont .....

	[..] last char vor der gro�en L�cke, Stand 160217
			 image_data_FontT24_0x002b[364]
			 __attribute__((at( START_T24_FONT + (1647 * 28) ))), START_T24_FONT  (0x08142F00 - MINUS_BANK)

			 -> frei ab 0x0814E490
			 geht dann weiter mit image_data_ostc_fuer_Tauchcomputer_240px
			 sind ca. 120 kByte frei!
