Fixed Issues since Linux Mint 19 BETA

All editions
------------

artwork:
  - mint-x:
    - no icons in Online accounts > Information about Gnome online accounts -> Gnome Contacts, Gnome Documents, Gnome Maps and Gnome Photos
    - visual glitches in mate-screensaver-preferences in the left pane (list of screensavers). Just move the mouse over that pane back and forth, without clicking. Doesn't happen with Mint-Y.
  - mint-y:
    - thunderbird icon isn't the same as its flatpak
    - in nemo additional pane, select a folder in the left page, click in the right pane. The selected folder in the left pane is white on grey, almost invisible.
    - video and subtitle icons are too similar

- The fortune command says 'no fortunes found' -> leftover, fortune is now removed.
- gdebi doesn't install packages unless it's run from the terminal
- ia32-libs: depends on libesd0:i386 which is gone
- libreoffice-base can't open databases

Cinnamon Edition
----------------

- goa: ubuntu SSO isn't functional -> it won't work without snapd, and it's useless for anything else. Ubuntu non-gnome users auth in snapd CLI anyway, so this should be removed. We don't need it, it's not necessary and it won't work OOTB.

------------

hidpi:
  - blurry titlebar buttons
  - grey tooltips

- mintlocale im has no window icon
- mintlocale has no window icon
- hide compton menuitem
- onboard isn't selected as a preferred apps

Xfce Edition
------------

- xfburn removed
