Restruct Silverstripe base/starter for new projects

Project setup

0. Clone repo
1. Remove .git directory
2. Remove README.md
3. Set DB credentials & various config etc in .env
4. Update project requirements and extra.expose in composer.json
5. Run composer update
6. Add favicon.ico in /public/

System:

Most html sections are wrapped in a common structure:

<section class="area-name-section">
    <div class="$ContainerClass"> <%-- .container equivalent/variant --%>
        <div class="outer"> <%-- .row equivalent --%>
            <div class="area-name typography"> <%-- .col equivalent --%>
                <div class="inner"> <%-- extra div for eg wells/boxes (while preserving column spacing) --%>
                    <p>(Actual content)</p>
                ...

Notes:

• app/ (project classes) are not namespaced as imo thats simply unnecessary/no use
• Default 'protected assets' folder is moved from /public/.protected/ to /restricted_assets/ (outside public webroot)
• Yarn unmet peer depencency warnings: https://stackoverflow.com/questions/46928390/#48767033

Optional modules

silverstripe/mfa
MultiFactor Authentication for SilverStripe (combine with TOTP authenticator module).

silverstripe/totp-authenticator
Time-based One-Time Password (TOTP) authenticator that plugs in to the silverstripe/mfa module.

silverstripe/session-manager
Allow members to manage and revoke access to multiple login sessions across devices. (Note: causes db write on every request by logged in members).

silverstripe/versioned-admin
Adds admin interfaces for managing DataObjects that implement versioning (history tab & Archive Admin UI).

silverstripe/versioned-snapshot-admin
Enhanced replacement for versioned-admin, adds snapshots to the history view (WARNING: experimental/unstable).

TODO

Based on Bigfork’s quickstart recipe, adapt some more functionality:

• webpack image compression (adapt bigfork)
• Adapt parts of public/_deact_htaccess
• Deployer (deploy.php & deploy/ dir)
