Deprecated code

I made a patch that fixes the deprecated function calls, removed the PHP4 idiom, prevented another undefined variable notice and fixed a few visual glitches: https://cl.ly/code/4112171Q3q1S

Thanks @till, fixing those has been on the todo list for quite some time!

And I’ve just checked those most of those changes into trunk. I’ve left the CSS ones as I have to investigate what each one does.

Hopefully we’ll get a new release out this week. Thanks for your help!

The CSS changes are based on WP 3.6 and are: 1) hide #wpfooter and adjust margins in iframe/popup 2) corrected visual glitches of the answer options in the “save” meta box 3) removed fixed height of the “poll style” box
