Add support for Arduino 1.0...

Add support for Arduino 1.0.  Most of this update has to do using the
latest [`ArduinoBuildContext`][1] from the [`arscons`][2]
[`site_scons.arduino_build`][1] module.

Add comments to `RemoteObject.cpp` packet-parsing code.

Merge branch 'arduino-1.0' of http://microfluidics.utoronto.ca/git/dmf_control_board into arduino-1.0

See #38.

Expose most `config_settings_t` attributes as Python class properties,
which can be read/written as attributes.

TODO: The `a[01]_series_(resis|capaci)tance` Python attributes are
currently available for _reading only_.  Setter methods need to be added
to complete ticket #38.
Add setter for channel R/C attr lists...

Add setter for `a[01]_series_(resis|capaci)tance` Python attributes.

Fixes #38.
Rename EEPROM methods/constants to PERSISTENT...

Rename `EEPROM...` methods/constants to `PERSISTENT...`, since not all
devices use EEPROM for persistent flash storage _(e.g., Arduino
[DUE][1])_.

__NB__ Execute `LoadConfig` after every `SaveConfig` operation to ensure
the most up-to-date values are loaded into the `config_settings_t`
struct in memory.

Rename all EEPROM Python refs to PERSISTENT
Add spacing around operators, after `if`/`for`.

Plugin modifications
====================

  * Clean-up plugin class code according to PEP8.
  * Use control-board attributes to update calibration settings, rather
    than modifying EEPROM directly.

Plugin modifications
====================

  * Clean-up `Feedback` class code according to PEP8.
  * Use control-board attributes to read/update calibration settings in
   feedback.
