Welcome message should update after successful login

[emfluenceindia]

After I login the Welcome message should ideally get updated. Currently it is not and using the same resource key. This is how we can do this:

1. Create a new key-value in BugNet_HostSetting table. Key could be something like "WelcomeMessageUser". The record could be added in the installation procedure as well by adding a new SQL INSERT inside BugNet.Data.SqlDataProvider.Sql file.
2. Create a new key named WelcomeMessageUser in HostSettingNames.cs enum.
3. In default.aspx.cs inside else part we can update the value of WelcomeMessage label

if (!Context.User.Identity.IsAuthenticated){
     ... ...
}
else{
     WelcomeMessage.Text = HostSettingManager.Get(HostSettingNames.WelcomeMessageUser);
     ... ...
}

Please let me know what you think.
