node-sass sometimes hangs because of how it works natively

[kenotron]

We will apply the workaround presented here for the sassTask:

https://github.com/sass/node-sass/issues/1048

It basically attaches an "uncaughtException" handler for process during the run of the sassTask. It cleans up this kind of workaround so other tasks won't have to deal with a "subpar" output from that workaround for other exceptions thrown.
