Plugin API: Can't insert button to editor

[marcosdsanchez]

I've just started using gtg yesterday and it worked great.

Today I open the program after doing my regular updates in my archlinux machine and noticed that tasks where not correctly added.

Exception trace:

I think this was caused by UI redesign by @jakubbrindza. We need to fix plugin APIs

As short term solution: you might want to disable plugins

[marcosdsanchez]

Disabling plugins worked. Thanks @izidormatusov

Let's just consider this is going to be nuked as part of #222 eventually.
