I suppose the main question is whether we want a 
project-save-some-buffers (one that can iterate through unsaved buffers 
but can also save them all with an extra keypress) or a straight copy of 
Projectile's command that just saves all buffers.

I don't use the iteration ability often, but once in a blue moon it does 
come in handy. Though perhaps one can continue using save-some-buffer 
for that (with the default predicate or not).
