Acronym expansion deletion

If you delete acronym expansion it should also deleted from posts.
Until then you have to do it with something like:

UPDATE `core_message_posts` SET `msg_post` = REPLACE(`msg_post`, '<abbr title=\"Too long; Didn\'t read\">tldr</abbr>', 'tldr') WHERE INSTR(`msg_post`, '<abbr title=\"Too long; Didn\'t read\">tldr</abbr>') > 0;

UPDATE `forums_posts` SET `post` = REPLACE(`post`, '<abbr title=\"Too long; Didn\'t read\">tldr</abbr>', 'tldr') WHERE INSTR(`post`, '<abbr title=\"Too long; Didn\'t read\">tldr</abbr>') > 0;
