* Moved template eval error handling to ManageErrors, where its 5KB of code won't get in the way of everyone, especially if template evals are disabled. (ManageErrors.php, Subs-Template.php)

- An unused global had slipped through my web, becaue of a false false positive. (Subs-Template.php)
! $txt caching was broken with a global removal. (Subs-Template.php)
- Removed $sourcedir entirely, replaced by APP_DIR. Fixed some SSI issues in the process. (SSI.php, index.php, Load.php, ManageErrors.php, ManagePaid.php, ManagePlugins.php, ManageSearch.php, Subs-Admin.php, Subs-Captcha.php, Subs.php, Aeva-Embed.php, Aeva-Gallery2.php, ManageMedia3.php)

* Another $boardurl to ROOT. Also removed ROOT_DIR being redefined (discarded error.) (QueryString.php)
* Attempting a flex-less design for banners which should work better across IE browsers. Always them, uh..? (index.css)
! Oh, yes, Wine also needed some extra help... I previously tried absolute positioning and then gave up on it, but in the case of Wine/Warm, doing it on the container (rather than h1/slogan) at least allows proper vertical positioning. (Wine/extra.css)
