[seam-dev] Seam common module

[Shane Bryzak]

We need some place to put utility classes that are shared across the 
other modules, such as Strings, Base64, etc.  For now, I've added a 
common module which is currently very minimal (which we can add to as 
required), however I'm not sure if this is the way we ultimately want to 
go.  I can't currently think of any alternative though - does anyone 
else have an opinion on this?  If we go down this route, then we will 
probably be able to do away with the root /common directory and just 
have modules/common instead.  Actually the more I think about it, since 
we are restructuring everything into modules anyway it doesn't make much 
sense to have a root common directory at all.
