[Xon] Full Message Text Permission 2.3.0

Adds permissions to include full message text in emails, per usergroup.

Works with:

• New thread
• Reply to thread
• New Conversation
• Join conversation
• Reply Conversation

Always email watched thread notifications, instead of last visit.

• Per-forum permissions.
• Per-user opt-in.
• User registration default.

New Options under 'Full Message Text Permission':

• Full Message on Warning Conversation Emails
  • Always send the full text of a conversation created when a member if warned.
• Max partial message text length
  • If the user does not have permission to include the full message text; this number of characters of the message can be send instead.
• Max all message text length
  • If the user does have permission to include the full message text; this number of characters of the message can be send instead.
• Allow always emailing watched threads
  • Default off, as there is a minor performance hit due to extra decoding that happens regardless of if the forum supports always sending watched thread notifications.

Three permissions:

• Full message text notification emails (conversation)
• Full message text notification emails (posts/threads)
• Always email watched thread notifications (posts/threads)

These will override the "Include full message text in watched thread/forum notification emails." or "Include full message text personal conversation notification emails." options.

Option to always send emails triggered by warning conversations in full. Consider my other addon; Warning Improvements by Xon to always send emails when a warning conversation is created.
