This seems to be unnecessary and screw things up on other platforms.

Revert "Separate toolbar guidance strings for easier localization"

This reverts commit 5da9b4bbb652f305dfe5bd77cae43422bc4a9f8c and uses
slightly different wording between the two messages ("Click here…" vs.
"Click the icon…").
Restore panel auto-hide and increase show delay to 2 seconds

I think requiring everyone with Zotero installed to manually close the panel is
just too annoying. (Not allowing the auto-hide for a couple seconds after
opening to prevent accidental closes would be nice, but preventDefault() in the
panel's onpopuphiding() doesn't seem to work, nor does changing noautohide
after opening.)

Increase the delay to 2 seconds to try to show on top of the Firefox 28->29
upgrade panel on slower computers.
Update versions
Fix display of missing data directory startup error in Standalone
Fix Redo via Cmd-Shift-Z in notes on OS X
Redo instead of toggling Z pane in text fields (except search bar) on OS X

Previously Cmd-Shift-Z worked for redo in text areas (Abstract, Extra)
but would toggle the Zotero pane in regular text fields. This change
allows Redo to work as expected.

The search bar gets focus when you first open the Zotero pane, though,
so we don't redo there, since it would be annoying if you couldn't close
the pane immediately with the same shortcut.
