Added support for custom meta tags via a new config file.
Custom meta tags will only be active if "CUSTOM_META_TAGS" is set to "true" in the config.
Replaced "<html lang="en">" with "@include('layouts.lang')" meaning HTML lang can be changed in the new config, defaults to en if not active or not defined.
I re-enabled the footer disabled by Latuminggi's LittleLink Admin fork. This footer adds a Home button which brings you to the landing page, in addition to Terms, Privacy and Contact buttons.
I also edited the policy pages for the buttons named above to include the new logo as well as the dark mode detection.
As part of the new logo (https://github.com/JulianPrieber/littlelink-custom/milestone/1) I'm now using the new 'logo.svg' vector logo.
For this, I added an if-else statement in most cases, which first check for a custom logo uploaded by the admin or the avatar of an individual user. If the image doesn't exist, the default logo (logo.svg) is used.
