Automatically create in current directory

[bnnk]

Hi all,
Recently, I created a script that allows to automatically install quasar with a couple of custom settings. To make the script compatible
with create-quasar, I added a small feature which allows to create the project on the current directory without asking the directory to
choose. This allows to create scripts that can add additional features to the Quasar installation.
Here's the PR which has my change: #15720
