[BioC] convert library for microarrays data

[Alastair Droop]

I found the bioconductor message annoying enough to track down and remove.

The message is displayed from within the .onAttach function within the 
Biobase package.

File: $RHOME/library/Biobase/R/all.rda (On my intel MAC)

Commenting out the message lines stops the startup message.

1) Backup original all.rda
2) Clear all packages from the search path except "package:base" and 
".GlobalEnv"
3) load all.rda
4) paste in altered .onAttach function
5) save(list=ls(all.names=T), 'all.rda')

I'm sure there are better ways of changing one function within a data 
file, but this one worked for me.  Hope this helps!

Alastair.
