findSkill by data class is not compatible with intent skills

[mvn23]

When creating a new profile with any intent-type skill (activity, broadcast, service), that skill always gets saved as an activity.
I tracked it down to be caused by the fact that the plugin is looked up by comparing the data storage class to that of all plugins, but all intent-type skills use the same data storage class (IntentOperationData).
Unfortunately I lack the skills to prepare a fix for this issue.

To reproduce, create a new profile with either a broadcast or service skill attached to it. Save it, then edit it. It is now loaded as an activity instead.

Thanks for spotting this! That's very clear explanation.

That mechanism is indeed problematic. I'll improve it soon.

In the meantime, bear in mind that there are also some issues with the service operation -- not in the way they work, but in the way they receive specifications. I was trying to provide a better unified operation for them, but did not progress far enough.

Hi. Does this issue still exist on v0.8.2.3-beta2?
I hope this is fixed by 17556ca.

A quick test indeed confirms the fix! Awesome!
