remove qt from Ubuntu GNOME seed

[Tim Lunn]

We really don't want qt5 on our default install, currently its being pulled in by fcitx and maybe evolution-data-server. This needs to be fixed, but perhaps to late for 16.04, so will target the 16.04.1 images.

I think the Ubuntu single signon used in the Software app for reviews and purchases depends on qt. :(

This bug was fixed in the package evolution-data-server - 3.21.90-0ubuntu3

---------------
evolution-data-server (3.21.90-0ubuntu3) yakkety; urgency=medium

  * Don't have evolution-data-server-online-accounts recommend
    signon-plugin-password (LP: #1571942)

I filed a debian bug ages ago re fcitx (can't find it atm, I will try dig it up later).

Basically the debian accessibility guys were against my proposed changes.

I might have fixed this; I'll see what happens for the next germinate run.

The Ubuntu GNOME 16.04 images doesn't include fcitx. The only thing bringing Qt in was that evolution-data-server-online-accounts recommended signon-plugin-password. That's fixed for yakkety:

For the live seed, I copied Ubuntu's live seed which gave us extra languages and fcitx. To get qt off though, I made these changes

- thunderbird locales (not related to Qt)
- fcitx-frontend-qt4
- fcitx-frontend-qt5
- fcitx-ui-qimpanel
- fcitx-mozc
+ !fcitx-frontend-all (blacklisted so we get the alternate recommends instead)

I could have kept fcitz-mozc and just blacklisted its gui config tool (which is written in Qt) but I guess Japanese typists can either use ibus or install fcitx-mozc themselves if they want it. The mozc config tool has a really ugly icon in GNOME Shell anyway…
