Build option to create lisp image

[justinmeiners]

The usual way to build common lisp apps is to build an image, so each program has its own copy of the interpreter/compiler. I did quite a bit of work to make sure my app didn't work this way, however the tradeoff is it has a little bit slower start up time then is necessary. This can get annoying when doing frequent builds.

Perhaps an option should be provided to build a standalone image, for those who are interested.

@eihli I really appreciate your thoughts and contributions. What do you think about this? Would this help you?

I haven't been doing builds frequently enough that the slow start up feels hindering. I'll keep in mind that this is an option. And thanks for the vote of confidence. Fair warning: I'm still really new to Lisp, so what helps me might not be in the interest of the average user.
