[evolution-patches] patch that fixes #42376 (evolution-exchange)

["Jain Vivek" <jvivek novell com>]

Hi,

The attathced patch fixes bug regarding allowing rename/delete of
standard folders in exchange.
http://bugzilla.ximian.com/show_bug.cgi?id=42376

I have made changes in storage/exchange-account.c.
Just checking whether the uri of the folder renamed matches any of the
standard folder's.

Thanks,
Vivek Jain
