Move last-cache, -mirror, etc. into setup.rc

[maphew]

Setup.exe has moved it's settings for last-mirror, last-cache, etc. into a single file: ./etc/setup/setup.rc. We need to do the same to maintain compatibility.

@jef-n, I'm 3/4ths through adapting apt to read and write etc/setup/setup.rc. On write, I want to make sure I don't mess up Setup.exe. What happens when it encounters an unexpected value? I'm thinking the most likely one would be 'None', which would occur if a person installs osgeo4w with an apt-from-scratch, followed by Setup.exe.

mirrors-lst
        None
window-placement
        None
last-mode
        None
last-mirror
        http://download.osgeo.org/osgeo4w/
net-method
        None
last-cache
        C:\Users\Matt\Downloads
last-menu-name
        OSGeo4W_default

Should I leave this as is, write the None's as blank lines instead, or just leave the empty entries out entirely?

Take the Setup.exe, Install a small package and use the values written...

What exactly is missing with setup.rc?

As I recall saving the globals to the rc file works, but at startup the rc file is ignored. So if someone runs Setup.exe and chooses different values, Apt will overwrite them from the older pre-rc cache files. I haven't tested what happens when the old cache files don't exist.
