RichTextBoxAppender

Based off of the work found here: http://osdir.com/ml/log.log4net.user/2008-04/msg00023.html

All credit goes to this post, just added some modifications I thought would be usefull.

#WindowsForm Example:

public frmForYourHealth()
{
    InitializeComponent();
    RichTextBoxAppender.SetRichTextBox(rtbLogging, "RichTextBoxAppender");
}

#ConfigFile Example:

<log4net>
  <appender name="RichTextBoxAppender" type="log4net.Appender.RichTextBoxAppender, RichTextBoxAppender">
    <mapping>
      <level value="WARN" />
      <foreColor value="OrangeRed" />
      <isItalic value="true" />
    </mapping>
    <mapping>
      <level value="INFO" />
