Create site alias automatically

You can obtain the alias for the active site with:

drush sa @self --alias-name="foo" --full --with-db

Nifty. Maybe we should do an example shell alias for that?

Here's a simple alias that defaults the name to 'new'.

Maybe we omit the name 'new' and expect people to use an argument? Commit this with or without that.

Does the site-aliases feature support argument-to-option conversion? If I remember correctly, it works like bash aliases, and appends arguments to the end of the expanded command line. If that's the case, then we could expect people to type self-alias --alias-name="myname", but we could not support self-alias myname.

The former works even if there is a default --alias-name in the site alias. Without the --alias-name in the site alias, the name would default to "self". I put the --alias-name in the definition to document the option.

Went ahead and committed #4.

Is there any way to reference to the actual folder as an alias even if its an empty folder.
I think this would make sense when creating a test environement of a live site

mkdir testlive
cd testlive
drush rsync @live . <----- not this is where I don't know how to reference

@current
. simply a dot
@self -> this doesn't work since it's an empty folder error message Could not evaluate destination path @self.
