Maybe fix note overwriting with embedded images in notes

But given that I can't really reproduce it, this is more of a guess.
Fixes #343, Add Item by Identifier textbox is truncated on second open
Fix conflict with Cmd-Shift-A, and probably other third-party shortcuts

The Zotero shortcut keys, and their event.preventDefault(), were bound
to keydown, so shortcuts bound to keypress were still be called. This
moves most of the shortcut handling code into the keypress handler.

Fixes #344
Closes #291, Default to last-used item type when creating item via
keyboard
Update to citeproc-js 1.0.469
Don't update Date Modified when syncing related items

This caused all items with related items to lose their Date Modified
when synced down.
Restore ZFS quota warning

Possible that this hasn't shown since 4.0?
Avoid unnecessary scrollbar in sync error panel, and remove height hack
Update to citeproc-js 1.0.470
Update locales from Transifex
Update repotime, submodules, renamed styles, and versions
Move TinyMCE into resource://

This fixes CSS in popups and probably other things.
Zip as much as possible in ZSA without repacking omni.ja, part 1
Fix handling of multiple missing/corrupt citations when "No" is clicked
Add Publication Title to title/creator/year search
