Unit Tests for i18n and wptexturize

[miqrogroove]

There are some predictable bugs not being tested yet:

$apos = _x( '’', 'apostrophe' );
$closing_single_quote = _x( '’', 'closing curly single quote' );
if ( "'" != $apos )
    $dynamic[ '/(\S)\'([^\'\s])/' ] = '$1' . $apos . '$2';

By that logic, quotations with outside punctuation will never work correctly.

'This is a test quote'.

becomes...

{$opening_single_quote}This is a test quote{$apos}.

It is easy to miss this bug because closing quotes and apostrophes are identical by default.

The regexp might need another tweak. The bug is fixed for a period outside the quotes, but commas and other chars might be common too.

Fixes more bugs. Adds more unit tests.
