Alright, this should be the last fundamental change for

devel/arduino-builder. =)

Right now, there's two possible configurations for building and
flashing Arduino projects:

1.) Use devel/arduino16 -- this pulls in devel/arduino-builder and
devel/arduino-tools itself, and uses its own method (as it turns
out, completely different from arduino-builder's discovery mechanism
=() for finding the proper utility for flashing (devel/bossa vs.
devel/avrdude)

2.) Use devel/arduino-builder + devel/arduino-tools directly, flash
the result yourself -- this has the pro of not requiring Java to
build a project, but the con that you do have to figure out how to
flash the board (w/ devel/bossa or devel/avrdude) yourself.

I suspect that #1 will be the most commonly used configuration, but
#2 is nice for "advanced" (or not-so-advanced) applications (such
as using a Raspberry Pi to compile+flash firmware for a 3D printer
=)). As such, we add an OPTION to make this a more straightforward
process of install devel/arduino-builder and then Just Do It.

This option will also add in a file at arduino/arduino-builder.options
that can be passed into arduino-builder through the -build-options-file.
This removes the need for -hardware, -libraries, and -tools flags
based on the defaults for devel/arduino-tools. This also auto-populates
the core version ("runtime.ide.version", -ide-version/-core-api-version,
and the ARDUINO #define) with the minimally supported version (see:
_COMPAT_VER, _IDE_VER -- these should be kept in sync, and correspond
to versions of devel/arduino-{core,tools})
