Created Issue: MaskedEditValidator.cs exception doesn't cause an validation failure [27179]

A date ending in all zeros doesn't cause an error in MaskedEdit validator. In short, 01/01/0000 should show the MinimumValueMessage but doesn't.

<asp:MaskedEditValidator MinimumValue="01/01/1900" MinimumValueMessage="<b>Out of Range</b><br />Date of Birth cannot be before 01/01/1900." MinimumValueBlurredText="*"/>

The root cause is System.DateTime.Parse throws an exception since c# MinDate is January 1, 0001.

The exception causes the validator to NOT call the callout.

I propose that line 795 of ./Server/AjaxControlToolkit/MaskedEdit/MaskedEditValidator.cs

case MaskedEditType.DateTime:
case MaskedEditType.Date:
case MaskedEditType.Time:
{
DateTime dtval = System.DateTime.Parse(Target.Text, ControlCulture);

becomes:
case MaskedEditType.DateTime:
case MaskedEditType.Date:
case MaskedEditType.Time:
{
DateTime dtval;
try
{
dtval = System.DateTime.Parse(Target.Text, ControlCulture);
}
catch
{
// a 0000 year causes an exception, set to MinValue
dtval = System.DateTime.MinValue;
}

I'm not sure whether there's other places which would need to be changed and whether this is the optimal approach. It's working for me.
