[Cosmo-dev] New login service (snarf rebuild required)

[Travis Vachon]

Hi folks

To enable the "log me into me home collection automatically"  
functionality, we needed a new authorization service. This had  
actually been in the works for a while, since we needed it to remove  
some really ugly hacky code from our login page, so this is a nice  
bene for 0.6.

The page a user is taken to on login is now determined as follows:
1) If the user was trying to access a page (say "/cosmo/admin/users")  
they'll be forwarded there
2) Otherwise, the server will look up the value of the user's  
preference named "Login.Url" and forward there
3) If that can't be found, the server will forward the user to  
{baseUrl}/account/view

The default urls and name of the preferred login url preference key  
are being kept in cosmo.properties. This means that after I check  
this stuff in you'll need to either:

a) Rebuild snarf
or
b) Copy snarf/src/main/config to snarf/dist/osaf-server-bundle-0.6- 
SNAPSHOT-/osaf-server-bundle-0.6-SNAPSHOT/etc
