MATE Session Dialogs: A little more traditional

[lah7]

If you use MATE and like traditional dialogs, @thesquash made a patch last year to make them look more like GTK2.

Before	After

Unfortunately, this wasn't accepted upstream (mate-desktop/mate-session-manager#261) due to code disagreements of the progress bar, the button design (vs theme) and possible accessibility issues, but it's fully functional and I'd say good work replicating the classic look & feel!

Here's the diff that can be applied to a copy of the source code. If using Arch, you can grab the PKGBUILD (arp checkout mate-session-manager), add a line in prepare() to apply the patch, build and install!

For Ubuntu (MATE) users, we could create this as an upgradable package in ppa:lah7/gtk3-classic, but do let me know!
