Replaced MODX logo in setup
[#9080] Separate open and close tags in modX::$sanitizePatterns

The single regex for filtering the modx tags was not sufficient for cleaning all nested combinations. Separating them into open and close tag pairs makes it much easier to completely filter the tags.
[#9080] Fix modX::stripTags() bugs allowing script execution vulnerability
Adjust nesting value accidentally left at 99
Make sanitizeRequest handle GET vars as arrays
Set allow_tags_in_post false in default System Settings

This should ONLY be true in Context Settings for mgr or any Contexts that need to provide the ability for users to POST MODX tags, numeric entities or script tags in requests to those Contexts.

Also fixes the description which erroneously indicated that when false, HTML tags were stripped from the POST. Only HTML script tags, numeric entities, and MODX tags are stripped from the POST when this is false. NOTE that this is ALWAYS done to $_REQUEST, $_GET, and $_COOKIE vars.
