Changes to M119 response for easier visual comparison

Changed to report on individual lines with "TRIGGERED" or "open" instead of "H" or "L" on one line as H&L could be confused with logic levels High and Low which may be wrong if using inverted logic.  Added strings to language.h.

Fixed typo "deu" in English language that was fixed in #134 but got added back in via 9f7f7354

Limit Switch locations based on MIN/MAX limits and homing direction

fixes #246
Added statements to set the limit switch positions to the maximum travel if homing in the positive direction as well as bed center at (0,0) if defined.
Relocated code based on feedback.

Slight modification for byte savings

Binary representation for characters in ultraldc.pde

Fix M81 not working reliably on Gen7

Added function 'setTargetedHotend' that turns into a function an operation repeated 3 times through the M-codes processing.

This modification saves a few bytes that can be used to add support for new commands.

The joris' char drawins are expressed in binary so to show their content's in a more visual fashion.

This is not a code modification as much as a readibility modification.

Missing #else in temperature.cpp prevented reading bed temp when TEMP_BED_PIN <7.  Thanks to Leland Wallace for helping me track this down via "Sesame Street" coding (what is not like the other)

Added PDF file containing Menu Tree for documentation purposes.  

Update Marlin/pins.h

Long filename support for LCD display

Implemented support for KILL_PIN / Fixed compilation errors for incomplete/bad translations

PLEASE BE MORE CAREFUL WHEN SUBMITTING NEW TRANSLATIONS

When you add new menu items / messages always copy them to ALL
languages (just use english)

The cli(); at the start of the kill() function also stops the internal
arduino timer which stops updating of millis() which prevents the
display of the "KILLED." message.
The new function updates the display directly without checking any
timers.

Added new function to the LCD menu.  Preheat settings now adjustable and can be stored

Added Menu Options to the Main-> Control->Temperature Submenu that allow the user to set new values for the ABS and PLA preheat function.  EEPROM updated so that these settings can also be committed to EEPROM memory.

- removed several multiple definitions of same message
- fixed definition of missing messages in german and spanish
- tweaked german translation (a lot)
