[ SEMANAGE] Resync seuser parser

Must keep the parsers in sync (or at least, the semanage parser should 
supercede the other one). Patch attached.

This is now perfectly valid on my machine (see below).
Loaded correctly, modified correcly, written back out in the same order, 
and straightened out into something sane.

test_user:root
                phantom:

        phantom:s0

__default__

        :user_u root:   root       :


s0


Test output
-----
There are 4 seusers before the transaction.

Now testing list...
Name: root, Seuser: root, MLS: s0
Name: __default__, Seuser: user_u, MLS: (null)
Name: phantom, Seuser: phantom, MLS: s0
Name: test_user, Seuser: root, MLS: (null)

Now testing iterate...
Name: root, Seuser: root, MLS: s0
Name: __default__, Seuser: user_u, MLS: (null)
Name: phantom, Seuser: phantom, MLS: s0
Name: test_user, Seuser: root, MLS: (null)

In-Transaction pre-commit iterate (should show modifications)..
Name: root, Seuser: root, MLS: s0
Name: __default__, Seuser: user_u, MLS: (null)
Name: phantom, Seuser: phantom, MLS: s0
Name: test_user, Seuser: root, MLS: s0:c5,c6-s2:c1,c3,c5

There are 4 seusers after the transaction

Now testing list
Name: root, Seuser: root, MLS: s0
Name: __default__, Seuser: user_u, MLS: (null)
Name: phantom, Seuser: phantom, MLS: s0
Name: test_user, Seuser: root, MLS: s0:c5,c6-s2:c1,c3,c5

Now testing iterate...
