add .cache/ to .gitignore

We don't need those files.

It's been a while since I've looked at quicklisp details. Can you please explain why it's OK to delete all of those files? Thanks

[bigos]

example from my system, it contains following

jacek@jacek-desktop ~/Programming/Lisp/hawk/.cache/common-lisp $ ls sbcl-1.1.1.0.debian-linux-x64

this page explains potential problems with pushing compiled code from development to production machine. http://common-lisp.net/project/asdf/asdf/Controlling-where-ASDF-saves-compiled-files.html

[bigos]

If your development machine uses different version of Lisp you don't need to push compiled lisp code to your production machine.

ASDF manual http://common-lisp.net/project/asdf/asdf.html#Configuring-ASDF section 3.3 has following:

Note that your Operating System distribution or your system administrator may already have configured translations for you. In absence of any configuration, the default is to redirect everything under an implementation-dependent subdirectory of ~/.cache/common-lisp/. See Controlling where ASDF searches for systems, for full details.
