Added "inputs" project

Added project, a stub sketch and the Fritzing diagram
Initial implementation of inputs sketch and diagram

Initial version of the inputs sketch from Chapter 3 of Arduino companion
Only print to console when the button is pressed.

Changed the sketch to stop spamming the console when the button state
is 0. Now, only pressing the button will result in a console message.
Base commit to setup Eclipse management
Added Eclipse management and build support. Created a version of
no_quarter that builds in Eclipse from C source instead of Arduino IDE's
.ino files.
Added documentation on Eclipse support.
Updated README to detail methods of building the sketch, now that
Eclipse is an option.
Added Eclipse version of the "outputs" project.
Added Eclipse support for the inputs project. Also corrected an issue
with the Arduino IDE, that will build both the .ino file and any .cpp
files in the same directory. Now, the .ino file is a blank stub for the
Arduino IDE to load a project from there. It will happily build the .cpp
files from the Eclipse project.
Made all .ino files empty stubs, as to make the Arduino IDE use the .cpp
files made Eclipse instead. Now implementation for each project uses the
same entry point and code, whether the Arduino IDE or Eclipse is used.
Updated inputs to control the on-board LED on switch button press.
Added strobe effect to switch press in "inputs"
