add support for flip disc devices

[GoogleCodeExporter]

support something like 14 x XY device (2x7 x XY)
1) implement 14h architecture
2) based on this, implement the device

should be 14v

do some testing with the u8g_flipdisc_2x7 device (console???)

C++:
U8GLIB_FLIPDISC_2X7 u8g();

/*
  Write data to the flip disc matrix.
  This procedure must be implemented by the user.
  Arguments:
    id: Id for the matrix. Currently always 0.
    page:   A page has a height of 14 pixel. For a matrix with HEIGHT == 14 this will be always 0
    width:  The width of the flip disc matrix. Always equal to WIDTH
    row1:   first data line (7 pixel per byte)
    row2:   first data line (7 pixel per byte)

device implemented

there is now a procedure to register the callback procedure:
void u8g_SetFlipDiscCallback(u8g_t *u8g, void (*cb)(uint8_t id, uint8_t page, 
uint8_t width, uint8_t *row1, uint8_t *row2))

todo
test and documentation
