Restruct Silverstripe Admin Tweaks module

This module serves as a portable set of small Silverstripe functionality & styling tweaks by Restruct., _(*1)

Currently it has been partially updated to SS4, most stuff is deactivated & will be reactivated when needed in projects., _(*2)

Functionality:

ImagePlaceholder functionality (SVG)
Contact & social media fields in SiteConfig (optional/configurable)
Raw html head/body tag fields in SiteConfig (optional/configurable)
Browser-chrome colorpicker field in SiteConfig (optional/configurable)
Provides a global $themeDirResourceURL ($ThemeDir replacement, eg: {$themeDirResourceURL('my-theme')}/videos/vid-{$RandomNumber}.mp4)
SSViewer_ExtraIterators (eg "col-2-of-4"): GroupSize, PosInGroup, FirstOfGroup, LastOfGroup, FirstLastOfGroup, GroupOfGroups
CacheHelpers::cached_http_request(), cached_json_request() & cached_jsonLD_request()
GeneralHelpers::safelyGetProperty() & download_and_save_asset()
Various stuff added to Page by PageHelpersExtension
ScheduledMethodCall class to call any method on a schedule using QueuedJobs module (if installed)
FormFieldBootstrapExtension to simply add .form-control class to formfields (optional)
FormFieldTweaksExtension to add classes & attributes to form holders only (combine with ->setFieldHolderTemplate('FormFieldTweaks_holder'))
EnforceCMSPermission trait to have DataObjects require CMS access credentials for CRUD actions
GridFieldConfigs::editable_orderable()
SelectiveLumberjack class (fixes Lumberjack to NOT filter listview and also take hide_from_cms_tree (core functionality) into account)
Sets Session.cookie_secure true
Makes UserDefinedForm NOT save to server by default (GDPR)
Sets slightly higher image quality values & activates WEBP format (if webmen/silverstripe-webp-images is installed)
Activates MimeUploadValidator (if silverstripe/mimevalidator is installed)
Sets default ("cacheblock") cache to 24 hours & creates a "appcache" of 1 hour
Has some email config helpers (see "Email config" below)
Sets some image manipulation fallbacks in case methods are missing (legacy, focuspoint, cropper)
Sets a slightly more secure password policy
Activates googlesitemaps (if module installed)
Registers FeaturedImage & CurrentYear shortcodes (if shortcode module is installed)
Adds stylish pageicons for common pagetypes (font awesome icons)
(Bigfork:) Hides pagetypes that cannot be created & admin sections that clients rarely use
Hides CampaignAdmin & ReportAdmin in nav (rarely used by clients)
Groups RedirectedURLAdmin, ArchiveAdmin, QueuedJobsAdmin, SubsiteAdmin and SiteConfig nav-buttons under "Advanced" dropdown (if symbiote/silverstripe-grouped-cms-menu is installed)
Various Block (Elemental) tweaks (+ block icon/thumbnail preview route at admin/blocktypeicons)
Fix to make empty/unchecked checkboxes in editablegridfields submit data (eg unset)
Workaround checkboxes being unset by $form->loadData() when they dont have a 1:1 fieldname/relation on object (set attribute data-setactivecheckboxvalues to force a value onto checkboxsetfields)
...

Untested / dropped-in functionality

Stuff quickly copied into this module for portability but may need some tweaking/generalization before being actually usable:, _(*3)

IpAddressField formfield with IP validation (may currently be only usable in front-end, not sure)
