Remove tab-indexes for recurring todo form

[dnrce]

This issue number may also refer to the older ticket #128, now #1595.

Using the natural tab order makes the Create and Cancel buttons accessible.

Fixes #1371

I'm not sure I like this. We added the tabindex for a reason, mostly to fix tabbing in the edit form while the new rec todo form was on the page too. Please test (use) this change to make sure all works well for the new rec todo use case and the edit rec todo use case

The "new" form and the "edit" form both tab correctly for me in Firefox 17 and Chromium 22. What do you mean by "on the page too?" Is there some way to have them display at the same time that I'm overlooking?

(Actually, the edit form had the same accessibility problem which was fixed by removing the tabindexes there, too. I just updated the commit.)

@maddentim, could you please test this change, too?

Yes, this worked for me as well in both the edit and new forms. I tested it in chrome 23 and chromium 22 on ubuntu and on my windows vm it worked in ie8 and ff17. I can test later on an ie9 on another machine, but I would be surprised if it regressed from ie8... I think we are good to go here.

Thanks for the testing!
