Took out the ifdef when I split 1.4 out and forgot to permanently
define it for <=1.3.

Fix num of digits on LCD for E and Z axis.

Fixed wrong code (will not even compile when EXTRUDERS>2)

This reverts commit cb02c2f9.

The number of steps per mm often contains 4 digits before the decimal point and does not require precision greater than 0.1

fix LCD temp bed artifacts on power up ' B022/0.) -> B022/000 '

Create an explicit rule for building applet/Marlin.cpp.

Italian language support

It would seem that the pattern matches do not work when the source
file is created when make is running. The result of this is that it is
necessary to run "make" twice to build the firmware.

This adds an explicit rule without a pattern match for building
applet/Marlin.cpp it corrects the make behaviour at the cost of adding
a little redundancy in the Makefile.

Added Russian translation

Marlin v1

Remove unwanted artifacts in merge of bed-pid tree

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
