[cells-devel] celtk cleaning - foreign libraries

I modified the foreign library packages as follows to make it work on my machine. In a previous email, someone said it worked best (at least for cello) with tcl 8.5 so we might as well make that explicit on unix.

(define-foreign-library Tcl (:darwin (:framework "Tcl")) (:windows (:or "Tcl85.dll")) (:unix (:or "libtcl8.5.so" "libtcl.so")) (t (:default "libtcl")))

(define-foreign-library Tk (:darwin (:framework "Tk")) (:windows (:or "Tk85.dll")) (:unix (:or "libtk8.5.so" "libtk.so")) (t (:default "libtk")))

(define-foreign-library Tile ;(:darwin (:framework "Tk")) (:windows (:or "tile078.dll")) (:unix (:or "libtk8.5.so" "libtk.so")) (t (:default "libtk")))
