Fix: Original Truncate method show now be able to trim
Add: Added some more tests for Truncate by words to cater for tagsAsContent parameter
Fix: In original truncate, currentTextLength prop will be increased everytime a tag is added, this will fix an issue when tagsAsContent is set to true (it would have added an extra char per tag, which would have went over to the next word)
I was surprised when this method did not replace a `\r` character with an HTML break. I have updated it to not only replace `\n`, but also `\r\n` and just `\r`.
I think these cases should be considered because of [this SO thread](https://stackoverflow.com/questions/4824621/is-a-new-line-n-or-r-n).
The updated code will not replace `\n\r` with one break but with two.
I used [this SO answer](https://stackoverflow.com/a/8196219/2963111) to update the method.
```
[TestMethod]
public void ReplaceLineBreaksForHtmlTest()
{
var result = "foo\rbar\nbaz\r\nbiff\n\r".ReplaceLineBreaksForHtml();
Assert.AreEqual(result, "foo<br />\rbar<br />\nbaz<br />\r\nbiff<br />\n<br />\r");
}
```
