word_count() is not accurate when counting sentences with quotes

[DaveChild]

Issue transferred from Google Code:

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)

This was added to the code.
