Include php-gettext 1.0.7 into extlibs; loading it up if native gettext extension is not present.

This provides a pure PHP implementation of the gettext functions.

This should help get laconica running on shared hosting environments where PHP's gettext module may not be installed.
Also gets us one step closer to running on Mac OS X 10.5 with Apple's preinstalled PHP, which doesn't provide an easy way to add modules.
