Infobar l10n pass

- remove the close button outlet (unused)
- add a helper to hide the buttons and resize the text field to use the same.
- if no image, move the text field
- tweak the xib to make it clear the values aren't used
- tweak the xib to remove the NSEveryone image
- make the link text use the control's font so it matches what's in the xib and other infobar modes (if we ever had to tweak it).
- use the GTM helper for autosizing buttons
- reflow how we position the buttons/textfield for the button infobars so it updates the textfield once.

TEST=if you make the window skinny, any infobars that don't have buttons shouldn't reserve space for them.  the the plugin crashed info bar shouldn't show a bogus graphic (currently we have none set).
