Persistent selections to become optional

If you've tried 0.0.3 and hate the behavior of the persistent selections -- well, I do too :-) I'm probably going to make the selection part optional in the next release and turn it off by default; it's a nice idea, but I'm sure a lot of people will still want to use apt-get and dselect, and having aptitude fighting with those over whether a package should be installed is simply not acceptable. (the last straw was when it removed nethack because I had installed it using apt-get. No-one touches my nethack! >=) )
Hopefully the APT folks will add something similar to the core libraries so we can share this info with apt-get, capt, and so on. If not, I'll try to find a less invasive way to implement it..
