Installation as a npm package fails

[exsilium]

Installation of Pylon as a npm package fails due to the postinstall step and the different location of ace editor:

> [email protected] postinstall /Users/xxx/Projects/pylon_npm/node_modules/pln
> cd node_modules/ace; make clean pre_build; ./Makefile.dryice.js minimal; cd ../..; make worker

sh: line 0: cd: node_modules/ace: No such file or directory
