Started to extend the QUnit tests. See "Testing The DOM manipulation". Things aren't working though.
Tidied up plugin.txt.
Added string.trim() function to util.js.
Added getInnerText() function to qunit_test.js.
Two functions added to prettydate.js - format and update. Updated unit test script to handle those changes. Moved getInnerText to the test script since it cant' be found otherwise.
Shortened an expression.
