Delete button instead of/in addition to shake-to-delete

[instaviz-2009b@…]

I just worry that if I do a lot of deleting, I'll be doing a lot of shaking. [Ryan Schmidt]

The shake thing to delete shapes is really annoying. I keep shaking and nothing happens. I'd really prefer another gesture for that, e.g., two fingers double tapping the shape or whatever. [Benjamin Zeiss]

In the longer term, that becomes Shake to Undo with the Delete function accessible through an edit dialog like most programs. [Andy Dent]

Deleting by shaking arghh! A gimmick really and wasn't fun even the first time. A toolbar at the bottom would be much more useful with delete etc. [Pizza Cake]

I'm kinda annoyed with the shake to delete but that more of a nit. [F.I.g.m.e.n.t]

But I don't want to shake my iPad to delete every unwanted node. Having never used the iPhone version I can only assume that shaking is much easier and more natural on that platform. Because it renders the app nigh unusable on the iPad. [obligatory nickname goes here]

As stated in other reviews, the app really needs a better way to delete objects on the iPad. (Just add a delete button to the node settings!!). [lotush3]

(In [196]) Added delete/clear button in component settings (fix #116). Certain settings now appear without background lines e.g. method selection in import/export settings.
