MacOSX: Many small problems

[Yvon TANGUY]

- Preferences: Firefox icon is 48px, but unlike on Windows & Linux, this icon is not resized to 32px.
  The 32px is available for Firefox. But maybe not for others moz apps, like seamonkey ?
- No icon for protected dom storage (1.8.0 only)
- Preferences dialogue problems: too small (was partially fixed in 1.7.3, but in 1.8.0, some id have changed, so update the css)
- ibuttonicon: no visual change on overlay (1.8.0 only).
- ibutton & imenubutton (main cookie window): Buttons are too small.
- Main cookie window -> Toolbar: Adjust the borders left and top.
- Main cookie window: Not resizeable.
- If open directly the browser pref tab, the pref window height is almost 0.
- Toolbar button in the palette: Should use the 16x16px icon.

Preferences dialogue problems are mostly due to bugs in the preferences window (XUL type). I have been able to reproduce most of them in GNU/Linux, when setting "browser.preferences.animateFadeIn" to true.
On GNU/Linux and Windows, animateFadeIn is set to false by default, On MacOSX to true.
Theses problems (after lots of try, I wasn't able to fix it completely, but event the Firefox preferences dialogue have the same problems too. There is lots of bugs open in mozilla's bugzilla for that.

On addons.mozilla.org, need to warn MacOS users about this issue, and tell them to set this property to false. I need to test it too.
