[changelog] new project picker, embed tweaks

  • the ‘new project’ menu in the editor now gives you the same three starting project options as the community site

  • added ctrl-; as a search shortcut for vscode users

  • In embeds, the ‘edit in glitch’ button has been replaced by a fullscreen icon. Editing was only one of the reasons a person might want to open up the embed in the full size editor.
