word_count() is not accurate when counting sentences with quotes

[GoogleCodeExporter]

Here's the test case:

---
public function testWordCountWithQuotes() {
    $textStats = new TextStatistics();
    $text = "\"There should be seven words,\" said Joe";

    $expected = 7;
    $actual = $textStats->word_count($text); // value is 8

    $this->assertEqual($actual, $expected);
}

---

Here's a possible fix:

In the clean_text(), replace:

---
$strText = preg_replace('/[,:;()-]/', ' ', $strText); // Replace commans,
hyphens etc (count them as spaces)

---
with:

---
$strText = preg_replace('/[",:;()-]/', ' ', $strText); // Replace double
quotes, commans, hyphens etc (count them as spaces)
