Support config refresh on iOS4 wrt backgrounding

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Currently adwhirl will only refresh the config file when initialized.  With 
iOS4's backgrounding, this is less likely to happen.  We should probably 
support some config refresh when the app comes back from the background.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
iOS4

Please provide any additional information below.

Please, please fix this at your earliest convenience. Because of this issue, 
our apps can't take advantage of AdWhirl's primary feature: the ability to 
change percentages and priorities of ad networks on-the-fly.

Thanks!
Matt

Same problem here. The ad banner does not refresh anymore when the app comes 
back from background.

It is a big problem as the user won't probably click again on the same banner...

This issue has been fixed. Please download the latest AdWhirl iPhone SDK 
version 2.5.5 . Use the updateAdWhirlConfig method of AdWhirlView, or the 
updateAdWhirlConfigWithDelegate class method to request a config refresh when 
you app comes back from the background, for example, in the 
applicationDidBecomeActive method of your application delegate or by 
notification.
