bzr-gtk @0.100.0_3: update to 0.103.0

[l2dy (Zero King)]

Latest version is 0.104.0 on ​https://launchpad.net/bzr-gtk/, but livecheck only found 0.103.0.

Edit: These two versions seem to depend on gtk3. If the port couldn't be updated, livecheck should use ​https://launchpad.net/bzr-gtk/gtk2 instead.

[raimue (Rainer Müller)]

This update was long-time blocked by upstream: ​https://bugs.launchpad.net/bzr-gtk/+bug/1032995

I just re-rolled a patch I had lying around and I am going to attach it here, but the result is not usable for me as almost any command throws an exception. Upstream for bzr is dead as development was halted years ago, so there is most probably no use in reporting this upstream and I do not have the time/energy/interest to investigate myself.

For completeness, this is what I see with bzr-gtk @0.104.0 for almost all commands:
