Administration: Change default site tagline to an empty string.

This changeset replaces the default "Just another WordPress site" tagline with an empty string for new installations. The reasoning is:

1. Not all themes display the tagline;
2. Not everyone changes the default tagline;
3. When people don't see the tagline in their theme, they may not realize it is still visible in some places, like feeds.

The string "Just another WordPress site" and the related multisite string: "Just another {NETWORK} site" are now only used as a placeholder for the tagline admin option.

Fixes #6479.
