[maxcanna]

Added possibility to be displayed inside a UIPopover

I'm sorry, but I cannot merge this pull request until there is application code that exercises the functionality. Many people have provided patches or pull requests for iPad support but no one has yet provided iPad example code. This is important to me because I need a way to check against regressions going forward, and I personally do not use Kal in any iPad projects.

I don't have a problem with adding iPad support, but it is a low priority for me since I have no use for it. But if someone wants to modify one of the sample projects in Kal to support iPad, then I would fully support merging their code.

I'm using this fix and it works fine in my iPad app.
