* Remove reload options, new file/help menus, tools/log at bottom
* Further menus refactor: install handlers at template creation
* WIP: Further tune menus, add custom about window
* New About window, new help menu items, menu labels now i18n
* Default device name on registration is now computer hostname
The OS of the device makes sense for those of us testing across a lot of
different OSes. And maybe for a user with just one desktop device. But
most users with multiple desktop devices are using the same OS for both.
* About window: Only show window when content is ready
* Fix typo in app/menu.js
