Bug 8781: hiding of transfer page when it's useless

The transfer page is only useful when the system
preference "IndependantBranches" is Off of when the user
is a superlibrarian. Otherwise it can be hidden.

All tests and perlcritic pass.

TEST PLAN :
It's about testing the display of the "Transfer" link on "circulation-home.pl".
The link needs to appear if IndependantBranches is off or if the user is a superlibrarian.

1) IndependantBranches = Off, user is superlibrarian : link appears
2) IndependantBranches = Off, user is not superlibrarian : link appears
3) IndependantBranches = On, user is superlibrarian : link appears
4) IndependantBranches = On, user is not superlibrarian : link does not appear
