Found most errors

The reason why the data logging code gave lots of “does not name a
type” errors was because the component libraries must be manually
placed inside a separate libraries folder for the Arduino application,
not a user created libraries folder in the project.  Right now, there
should only be two errors: one where LPS331AP_ADDRESS_SA0_HIGH was not
declared, and one where mpl115a2 was not declared (Gus deleted the
setup for that sensor).
