[Tinyos Core WG] Updates to BlockStorage

[David Gay]

I've made the changes to BlockStorage discussed at the last telecon
for the at45db, they're checked in to the devel branch (I considered
making a different branch for it, but then only people with access to
the head would have access to it, if I understand CVS access control
correctly (doubtful)).

Note to Phil: can you send the list a summary of current CVS usage
procedures? I'm completely confused now :-)

Jonathan, let me know what your experiences with the stm25p are...
