Rewrite unit tests to not change the process's CWD, replace Traceur w…

…ith 6to5

Closes #86
Closes #87
Paving the way for #96 (allow APIs to receive a sitePath argument)

TODO check if build's copySrc is copying files which have been negated by globs before being re-included
TODO check why build task takes so long to finish when passing an absolute sitePath argument and CWD != sitePath (the `harmonic build`  in the unit test takes about 11 seconds to finish in Windows)
