IMP (4.1+) Hierarchical folder structure with Cyrus IMAP

Since IMP 4.1+ the previous hierarchical folder structure - personal folders below INBOX, shared folders beside INBOX - has gone, because it is not the correct way - according to the RFCs.
This has been discussed in Ticket #3004 and Ticket #2422.

Because some people still would like to have the folders presented the old way, here are patches to enable this - still working with HEAD from 16. March 2006.

I am not familiar with php and making patch-files - every suggestion would help.

A configuration option - ['server']['dont_strip_namespace'] - will be added to imp/conf.xml (update your IMP configuration after patching !), imp/lib/IMAP/Tree.php and framework/IMAP/IMAP/Tree.php (bring installed framework up-to-date after patching !) will be patched.

Use this at your own risk !
it is working fine for me with Cyrus 2.3.3, PHP 4.4.2, Apache 1.3.34 and Horde HEAD
