The changes I've made to SparklePlus (which someone needs to build  
and commit to the Adium trunk and branch) should allow us to have two  
(or more) entries in our appcast.  The most recent entry which  
specifies system requirements which are met by the system will be  
used.  So:

Released 5/30, 1.1, requires 10.4.0
Released 5/30, 1.0.6, requires 10.3.9

would do just fine.  1.0.5 needs to already be out there with the  
sparkle fixes for this kind of appcast to work properly.

Remaining problem with multiple entries in an appcast:

While running 1.1, the following appcast:

Released 6/1, 1.2, requires 10.4.0
Released 6/15, 1.0.6, requires 10.3.9

would report "no updates found" because 1.1 > 1.0.6, the 'latest'  
version.

Working around this at present just means that we need descending,  
not ascending, release dates -- which are just arbitrary strings not  
seen anywhere, anyways, so that's okay. A more elegant sparkle-based  
solution could be done, too, if someone has the mind to look at it  
(look at my changeset for [85] in SparklePlus and similarly move the  
versioning logic in there).

Cheers,
Evan
