Support for 644/644p and 1284p

[GoogleCodeExporter]

Atm. Optiboot uses the Sanguino core files, since they ar quite old, (made for 
Arduino 18) some things aren't working.
But when I change 
sanguinoo.build.core=sanguino:sanguino
to
sanguinoo.build.core=arduino:arduino
sketches get build, but strange things happen like the µC freezes or strange 
characters on attached LCD.

I don't understand.  Optiboot doesn't "use" the core files at all, as far as I 
can tell.  (I deleted the cores directory from the optiboot repository 
entirely, and the 644 optiboot still builds fine...)

the optiboot bootloader itself works fine, but the sanguino core files you 
provide are outdate ase those from sanguino themselfes. Seems this is mor their 
fault, not yours. Sorry, your only making the fine bootloader :D

It looks like the optiboot source tree and install directions cause 
possibly-obsolete core files to be used for the new platforms it defines (ie 
the core files that are part of the optiboot source rather than the arduino 
distribution.)  We should at least change the directions, I think.  Probably we 
should get rid of the "core" files included with optiboot.
