KDevelop: Add some propagatedUserEnvPkgs dependencies.

[ambrop72]

Now KDevelop should start in a functional form without having to
manually install those.

Is this necessary? All these packages are already added to the system path in modules/services/x11/desktop-managers/kde4.nix.

I don't see kdevelop on other distros depending on those packages. I wouldn't make things that are so easily pluggable to be bloated this way by default.

Are you implying that only KDE users could possibly use KDevelop for
writing a Qt app?

[ambrop72]

Some clarification, these are for:

• kate: The text editor component, KDevelop doesn't start without it.
• konsole: The embedded terminal.
• kde_runtime: The welcome screen, uses Plasma libs.
• oxygen_icons: Lots of icons not found elsewhere.

It's a shame we have to add these to the profile for KDevelop to pick them up though.

Can someone else confirm this? If KDevelop doesn't start without kate installed, we should fix this.
