Show technology mistakenly unlocking research

[cmears]

When I click on the technology in a recipe, the technology window isn't shown and instead the clicked-on technology becomes unlocked. The game gives this output:

  40.414 Script @__FNEI__/core/Debug.lua:98: [FNEI][ERROR] <FNCustomEvents>  FNEI: event  recipe sprite-button tech  return error!
  40.420 Script @__FNEI__/core/Debug.lua:98: [FNEI][ERROR] <FNCustomEvents>  LuaForce::current_research is read only.
stack traceback:
        __FNEI__/utils/open_tech_hook.lua:68: in function 'show_tech'
        __FNEI__/scripts/recipe/controller.lua:305: in function 'cur_event'
        __FNEI__/scripts/custom_events.lua:65: in function <__FNEI__/scripts/custom_events.lua:64>

        __FNEI__/scripts/events.lua:75: in function <__FNEI__/scripts/events.lua:72>

So I guess manipulating current_research in this way is no longer possible?

The hackish solution is no longer needed anyway, now that LuaControl::open_technology_gui() exists.

Fixed in 0.2.4.
