Three bugs within Usercp

Hello
I've reported three bugs on the bug tracker but then I noticed there is a forum section for it as well, so I might just mention it here as well.
Addon domain module creates vmail folders with wrong ownership that results in broken email account.

Email filter module creates sieve files with wrong ownership that result in inaccessible filters, possibly broken too.

Email filter module cannot browse/see all folders results in the module being almost useless if roundcube has access to all folders and can do the same job (after fixing the sieve bug)

Regarding bug #204:

I'd like to add that I just discovered that this issue is a bit more specific.

The issue is present when creating a filter set BEFORE going to the filter tab INSIDE roundcube.
Meaning:
- Create the addon domain. [Broken vmail folder. Fix before continuing, see bug#203]
- Create an email address for this new addon domain.
- Go directly into Roundcube, login, and then go to the filter tab under settings. Roundcube will create the filter set called "Roundcube". A sieve folder is created with the correct ownership.
- Now, whatever you do on the Email filter module inside the usercp, it will not break the filter accessibility.

But, the symlink created by the filter module of the usercp is still assigned wrong ownership, though it does not break it.
