Ui tweaks

This is a collection of minor UI tweaks I made after using this for a while.  I found that the buttons were too small on the new skinny iPod, so I kept hitting the wrong button; for example, I often stopped the video I was playing when I meant to fast forward.  There's also a straightforward fix for the initial connection being slow.  I haven't tested with the fr.lproj stuff that showed up after I did this and I don't know how to automatically merge the .xib changes to all languages.

These are too small to bother making a separate branch for each; feel free to cherry-pick what you want.
