Support for old browsers (IE lower than 9) and more configurations on

Problem/Motivation

I need to give support for IE older versions (specifically IE8) which does not support the :nth-child() pseudo selector.

Proposed resolution

Enabling the default row css classes of views would make styling easier, because we will use css classes instead of pseudo selectors.
This would also give us the possibility to have better configurations when editing the format settings that were hidden. The "Add striping (odd/even), first/last row classes" is now disabled and checked by default, in order to prevent breaking the UI.

Remaining tasks

This patch needs to be reviewed. I tested it, and it's being used on my site.

User interface changes

I've also changed the css class generated by the module (simple_timeline) to simple-timeline in order to make it follow the css coding standards.
