A few custom tweaks for the new ClassicPress Security page

functions.php

/**
 * Remove ClassicPress security page from admin menu and convert icon to text.
 *
 * Reasoning: After being initially in favor of the addition of a security page,
 * the implementation seems rushed and incomplete. Since I already have a plugin
 * for security, this means I have 2 entries for security in the top-level admin
 * menu. This action hook removes the needless core menu item. This doesn't kill
 * the security page's functionality; it only removes the admin menu item. For a
 * plugin that has registered security settings to be displayed on that page, it
 * will still have a "shield" icon on the plugin admin page leading to the right
 * security page.
 *
 * Bonus: Convert shield icon back into text link in plugin admin rows.
 *
 * For a variety of reasons, I don't care for the shield icon being displayed in
 * the plugin admin rows. It's not vertically centered, it has a divider next to
 * it which looks weird, there's 1 icon and the rest are text links, and it will
 * probably promote others to do the same with their own ideas about which icons
 * are suitable for what. Also, text is 100% translatable; icons, not so much.
