PID for heated bed

Spanish language updated

Dialogs from M119 translated, and "Set Preheat" dialogs adapted to the
screen size.

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

Some dialogs corrected and Default language set to 1
