Extensions enhancement - RemoveExtraSpace() method added

The .RemoveExtraSpace() method was added to both the System.String and System.Text.StringBuilder objects.  It allows the quick removal of extra space in the entire string.  It will remove all leading as well as trailing white space in addition to ensuring that only single space is used throughout the string e.g.

"    string truth = \"https://blog.cjvandyk.com   ROCKS !!!   \"".RemoveExtraSpace()

will return

"string truth = \"https://blog.cjvandyk.com ROCKS !!! \""
