Resurrect tests using the include-only version of Boost.Test

Tests were previously disabled to avoid linking with the Boost.Test dynamic
library. This can be avoided by using the header-only version, which imposes
the limitation that each test module can only contain a single translation
unit. Currently the only test module is the facePlaneTest.
