+/*	The job of this file is to handle everything related to posting replies,
+	new topics, quotes, and modifications to existing posts.  It also handles
+	quoting posts by way of javascript.
+	void Post()
+		- handles showing the post screen, loading the post to be modified, and
+		  loading any post quoted.
+		- additionally handles previews of posts.
+		- uses the Post template and language file, main sub template.
+		- allows wireless access using the protocol_post sub template.
+		- requires different permissions depending on the actions, but most
+		  notably post_new, post_reply_own, and post_reply_any.
+		- shows options for the editing and posting of calendar events and
+		  attachments, as well as the posting of polls.
+		- accessed from ?action=post.
+	void Post2()
+		- actually posts or saves the message composed with Post().
+		- requires various permissions depending on the action.
+		- handles attachment, post, and calendar saving.
+		- sends off notifications, and allows for announcements and moderation.
+		- accessed from ?action=post2.
+	void AnnounceTopic()
+		- handle the announce topic function (action=announce).
+		- checks the topic announcement permissions and loads the announcement
+		  template.
+		- requires the announce_topic permission.
+		- uses the ManageMembers template and Post language file.
+		- call the right function based on the sub-action.
+	void AnnouncementSelectMembergroup()
+		- lets the user select the membergroups that will receive the topic
+		  announcement.
+	void AnnouncementSend()
+		- splits the members to be sent a topic announcement into chunks.
+		- composes notification messages in all languages needed.
+		- does the actual sending of the topic announcements in chunks.
+		- calculates a rough estimate of the percentage items sent.
+	void notifyMembersBoard(notifyData)
+		- notifies members who have requested notification for new topics
+		  posted on a board of said posts.
+		- receives data on the topics to send out notifications to by the passed in array.
+		- only sends notifications to those who can *currently* see the topic
+		  (it doesn't matter if they could when they requested notification.)
+		- loads the Post language file multiple times for each language if the
+		  userLanguage setting is set.
+	void getTopic()
+		- gets a summary of the most recent posts in a topic.
+		- depends on the topicSummaryPosts setting.
+		- if you are editing a post, only shows posts previous to that post.
+	void QuoteFast()
+		- loads a post an inserts it into the current editing text box.
+		- uses the Post language file.
+		- uses special (sadly browser dependent) javascript to parse entities
+		  for internationalization reasons.
+		- accessed with ?action=quotefast.
