With multiple connections, emphasize need to provide name of connection.

This slight documentation change reflects discussion in GH issue 85.

Cf.: #85

Perhaps this phrasing:

Then, you can call the database keyword with the name of the database connection you want.

Note that if you define multiple connections this way, you'll always need to specify which connection you mean. Calling database() with no connection name will use the default unnamed connection details, whereas database($connection_name) will use a connection with the given name.

For example:

 my $default_dbh = database();

Thanks for the PR, and sorry for the slow reply. I've gone with a modified version of Josh's wording which I think clarifies it best - in particular, that you can still call database without a connection name, but that you'd get the default un-named connection details in that case.
