Remove glslify from the initial template

It's not necessary also makes things complicated for Electron as it depends on node.js being installed on the users machine.

I don't know if this is the right place for this, or even the right place for the fix. On win32 at least I had trouble because the require uri that glslify-promise transform was pushing was missing some directory parentheses, you end up with it looking for folders that don't exist because it's mashed together a uri like ..\node_modulesglslify-promisewrapper.js

Not relevant with new glslfiy
