Support creating project in current directory

[cecilphillip]

What problem does this feature solve?

Makes a step towards more easily using the 3.x CLI with other non-javascript backend projects such as asp.net or flask.

Currently, invoking vue create . in an empty directory throws the following error

🚀  Invoking generators...
 ERROR  Error: Cannot find module '@vue/cli-service/generator' from '/Users/cecilphillip/Desktop/toss'

What does the proposed API look like?

vue create . || vue create --here

Just tried doing this but couldn't get it to work.

It says "The batch file cannot be found" and then fails.

Currently running vue-cli 3.0.0-beta6.

Happy to create a new issue (if needed) and/or provide more info.

Replying to my own comment, it looks like it works correctly when I tried again and told vue cli to manually select features.
