src/clfswm-internal.lisp (current-child-setter): Store root current child before apllying current child change.

src/clfswm-internal.lisp: Remove the *current-child* variable and use a setfable function (current-child) instead.

src/package.lisp (make-x-drawable): Drawable wrapper to prevent type error in some CLX versions. Replace xlib:drawable-* functions with x-drawable-* equivalents

[PATCH] CLFSWM should depend on sb-posix since src/tools.lisp uses sb-posix:getenv & sb-posix:putenv.

src/clfswm-pack.lisp (move-frame-constrained, resize-frame-constrained): New function. Move and resize frame with the mouse constrained by other frame brothers.

clfswm.asd: Change compilation order to prevent undefined	variables. src/clfswm-internal.lisp (show-child(frame)): Handle properly the show-root-frame-p parameter. src/clfswm-util.lisp (move-frame, resize-frame): Do not move or resize a frame when it's the current root.

src/clfswm-expose-mode.lisp (expose-windows-mode, expose-all-windows-mode): Use a generic mode. src/clfswm-internal.lisp (child-position): New function.

src/clfswm-expose-mode.lisp: Move and rename present*-windows in a separate clfswm-expose-mode.lisp file.

src/*.lisp: Replace the case to handle event with a more (tricky) lispy  method which bind a function to each keywords associated to graphics events. Remove event handler hooks as they're not needed anymore (To replace them: use closure and define-handler).

src/clfswm-placement.lisp: New file. Allow to place info windows or query windows on an arbitrary place. Allow to bannish the pointer on an arbitrary place.

Massive update: Fast layout switch, switch to last child, color nearly everywhere (Help, keys...), simple way for corners configuration, auto-doc on corners, show configuration variables

Give a minimal size for windows. Center windows in the screen instead of in there frame. tile-space-current-frame bound on C-t.

produce-doc-*: Moved to clfswm-autodoc.lisp. Produce-menu-doc, produce-menu-doc-html: New functions.
