gulp-starter-env installer

Why

In the optic of made easier the starter environment for designers in open source, that @una is promotiong and helping with her gulp-starter-env, I am adding this little thing to launch something like an "installer" from the command line.

How

-1. Install jq, the only dependency, if you doesn't have it yet.

1. Download this file or copy paste on a shell file like install.sh
2. Allow permission to execute chmod +x install.sh
3. run ./install.sh and follow the instructions

Dependency

It is necessary to install jq to easily customize package.json

Todos

Just know that the script could improve so much...
