Depend on ign-msgs 8.2 and add QML dependencies

[chapulina]

@j-rivero , what do you think of adding these QML dependencies to a stable version? They're only needed by a new plugin, and they're only checked at runtime, not at compile time.

Sounds not a hard dependency although I see them listed unconditionally in build-deps inside the control file. Are they needed during build + testing?

Nope, none of the QML modules are. They're just loaded at runtime. Should I remove from Build-depends? All I'd like to do is that users get these dependencies when installing ign-gui, so the new plugin works out of the box.

Yep, build-dep should list build time dependencies including testing deps.

They are listed under the -dev package and will be installed together with it.
