Instead of adding a momentary switch to fake the insertion of the card I have modified the ultralcd menu item:

Card Menu -> Refresh

to reinitialise the card providing that the SDCARDDETECT pin has been set to -1 in the pins.h file.  This requires one less switch on the front panel and the refresh menu item is in the most relevent place for a user who wishes to inert a card and then print from it.

It also means that the "Card inserted" messages do not bother the users of these card readers (they dont make sense for users without SCCARDDETECT)

Added more defines to the language.h file so that nowe most of the text strings are now configured via this file.  Still got some hunting down to do to complete this task.

Clean up and add some trace info

Add explicit #define for bogus temp override

pins.h: Define Z_MAX_PIN for Gen7 board

V1.4 moves thermistor power to the always-on 5v line.
The BOGUS_TEMPERATURE_FAILSAFE_OVERRIDE is no longer
needed on this board.  Add a new motherboard type to
support this feature.

The code to ignore the "bad thermistor reading failsafe"
suicide function depends on the existing of the PS_ON pin
feature.  But in some boards this shouldn't be the case
Fix this by adding an explicit definition to make our
intentions more clear and separable.

The Z_MAX_PIN value was defined as no-value, but this causes
the compile to fail.  Fix this by setting the Z_MAX_PIN to the
correct value (which happens to be 0 for pin PB0/DIO0/0).

This adds flexibility to the makefile by allowing different pde
targets to be specified for different needs.

Fix build on Sanguino based boards with ATmega1284P

Fix Makefile

Included AD595 calibration options. (daid)

Split ramps1.3 in Sprinter like config and multiextruder config.

Added M221 extuder multiply factor.

I find that the PID routine works better when the cooling fan is switched on
at the beginning of a warm up routine.  Otherwise when you enable the fan
just before a print, you have a delay as the PIDre-adjusts.

This should also be safer as most cooling fans are directed at the hot -ends
thermal barrier!

Instead of a single pre-heat, now there is pre-heat ABS and PLA options
Added defines to the configuration file to adjust preheat temperatures for both

Updated the Xsteps ... settings via the LCD menu
