bsb.exe: unknown option '-color'.

[peerreynders]

With bs-platform 4.0.5 the -color command line option was removed from bsb.exe.

rrdelaney/bs-loader#47

To get past the resulting failing build it is necessary to update to the most recent bs-loader (2.0.6 which includes the corrected bsb-js@1.1.7).

$ cd ./node_modules/reason-scripts
$ npm update bs-loader
$ cd ../../

[rrdelaney]

Try reinstalling node_modules, it should pick up patch releases of bs-loader.
