Infinite loop in token matching if property references itself

[fabriciomurta]

Ext.NET does not nicely handle a token reference loop like:

<ext:Label ID="Label1" runat="server" Text="Contents here. :) [#{Label1.Text}]" />

Notice the label's Text property contain a token referencing itself. Ext.NET should nicely support handling cyclic referencing (for example, not trying to expand again the token, or using the replaced token instead -- or at least displaying a better descriptive error message.

The server error message raised is: Insufficient stack to continue executing the program safely. This can happen from having too many functions on the call stack or function on the stack using too much stack space.
