5 changes in one

I made 5 changes to the code that I unintentionally combined into one commit. So feel free to include only parts of this.

1) Removed the logic from the selectIndex method which did not work in all cases.
2) Changed the button type on the send tab from "touch up" to "touch down" which makes it easier to select the desired address.
3) Slightly decreased the tab change duration to improve the user experience.
4) Ignore the user specific workspace settings.
5) Removed some unnecessary code.

Also I was wondering if there is a more recent version as the code in the repo is version 1.9.8 while Cydia shows 1.9.9.
