[imp] Autoreply/Forward Code

[Rob Wiltbank]

Greetings folks.  Below is a contribution to the project to enable email 
forwarding and autoreplying for IMAP servers that do not, by default, 
support these features.

Here's how we are configured:
* IMP runs on a linux machine that uses a .forward file for forward emails 
and supports user procmail files.

* ftp is enabled (for localhost sessions only).

* Our authentication scheme is kinda freaky, but, in short,  we allow the 
user to authenticate if their IMAP passwords -or- their shell passwords 
are correct.  As long as the user has a shell account and their 
username/pass is the same for their email, this code should work.

How it works:
Using PHP's 4.2.3 ftp functions, we check the user shell account for the 
existing .forward or .procmail.webamil files to see if either are enabled.  
If not, it allows users to create one or the other. 

Other Notes:
Looking at the few pre-existing projects out there, the majority of the 
code was no longer functional due to updates to Horde or IMP that made 
several of the functions obsolete.  In this respect, I tried to create the 
code to be as independant as possible from Horde/IMP to allow it to 
function as long as possible.

Any feedback or suggestions are gladly welcomed as this is my first 
journey into attempting to integrate anything into the Horde project.
