Extend some useful string functions in C#

Add some useful extension methods for string manipulations in C#. Make coding more elegent, interesting and productive.

string.ToBoolean();
string.ToInt();
string.RemoveSufix(string suffix);
string.RemovePrefix(string prefix);
string.Remove(string toBeRemoved);
string.RemoveSpace();
string.RemoveWhiteSpace();
