[dev] Patch to conf.php.dist to fix bug in imp_show_quota example

Hi all,

In the exmaple of a imp_show_quota function, where you test the results
of the call to imap_get_quota(), the test is invalid. 

imap_get_quota returns either an array, or false. In IMP 3.1rc2 you use
the empty() function to test this. But empty() returns true if a variable 
is set to false. In the HEAD branch you use:

  if (isset($quota) && $quota['limit'] != 0) 

That's better, as it prevents divide by zero errors, if there is a quota. 
The isset() really doesn't need to be there, as it will always be set to
either an array or false. 

The documenation for imap_get_quota() suggests using is_array() to check
the return value. Attached is a patch against 3.1rc2 to add this, as well
as non-zero check.

Thanks.
