Add some rudimentary dependency tracking.

Add some rudimentary dependency tracking.

"tracking" is probably an over-statement.  What this does is to store a
package's run-time so deps (gleaned from ldd) in its .project.  The build
script template has been updated to find/store them, and functions have
been added to handy_funcs to view them.

I've also gotten rid of most of the uses of pinky in the aux functions and
simplified them.

	* etc/pkgusr/skel-package/.project (Deps): New.

	* etc/pkgusr/skel-package/build (update_commands): Add magic to
	find the run-time deps.

	* etc/pkgusr/handy_funcs (deps): Show the dependencies.

	* etc/pkgusr/handy_funcs (H-pkg): Add `deps'.

	* etc/pkgusr/handy_funcs (showinst,showgen,srepo,trepo,web):
	Remove unnecessary use of pinky.

	* etc/pkgusr/zsh/_zsh-pkgtools: Add `dpkg'.

	* etc/pkgusr/zsh/zsh-pkgtools (H-pkg): Add `dpkg'.

	* etc/pkgusr/zsh/zsh-pkgtools (dpkg): New.

	* etc/pkgusr/zsh/zsh-pkgtools (upkg,Lpkg,vpkg,ipkg,gpkg,wpkg,pkgrepo):
        Remove unnecessary use of pinky, sed, etc to simplify.

	* lisp/pkgusr.el (pkgusr-pkg-deps): New.  Bind `H-c D' to it.

	* lisp/pkgusr.el (pkgusr-pkg-url): Remove unnecessary use of pinky.

	* lisp/pkgusr.el (pkgusr-pkg-repo): Ditto.

	* lisp/pkgusr.el (pkgusr-pkg-version): Ditto.

	* lisp/pkgusr.el (pkgusr-pkg-description): Ditto.
