v0.2.0

• New "account" and "splash" pages. We will share more on these new pages in upcoming blog posts.
• Added "is_email_verification_required" argument to global_sessions_config() that allows you to disable email verification.
• Admin Panel > User Access - added a checkbox to send an email invite to a newly newly invited user
• removed usage dashboard from "Admin Panel". This dashboard has been superseded by the dashboard at
  https://dashboard.polished.tech (#102)
• added "background_image" argument to sign_in_ui_default() to allow for a full screen image for the sign in page background.
• only use the "email" sign in provider by default rather than c("google", "email")
• added customizable sign out button to secure_static() (#93)
• standarized and documented process for using fully customized sign in and registration pages (#92). New functions sign_in_js() and sign_in_check_jwt(), and new vignette on how to use these functions to create fully customized sign in and registration pages.
• add sign_in_module_2 as an alternative premade sign in page. sign_in_module_2 is designed to look nice when using social sign in
  providers (like Google and Microsoft) in addition to email/password.
• Removed sign_in_no_invite_module. sign_in_module and sign_in_module_2 now have an "is_invite_requirement" argument, so there is no longer a need for a dedicated sign_in_no_invite_module.
