Fix dependencies

[purcell]

Neither eieio nor tabulated-list are installable packages, so depending on them leads to odd installation failures in some cases: purcell/emacs.d#255

This commit declares a dependency on Emacs 24 instead.

Sorry, my mistake. Sent to a wrong project.

I'm going to accept that because I don't want to support emacs 23 anymore, but that sounds like a package.el issue really (well, the "odd" part anyway, installation failure has to be expected): dependencies that package.el doesn't know how to resolve are a fact of life and should be dealt with gracefully.

Note that tabulated-list is installable, I explicitly made sure of it: https://marmalade-repo.org/packages/tabulated-list
It's just that not every ELPA repository knows about it.

Yeah, I agree it's not ideal. The main problem here is that eieio is uninstallable, so Emacs 23 users would see that dependency failure and go looking for it, only to discover that it's built-in in Emacs 24. So changing the dependency makes that more explicit.

Cool -- where does the backport live? I can add it to MELPA.

@purcell the backport is here: https://github.com/sigma/tabulated-list.el

Oh - my mistake: we already have it: http://melpa.org/#/tabulated-list & http://stable.melpa.org/#/tabulated-list.

Thanks!
