Suggest commands of immediate use

[Chrezm]

Describe the current situation: Currently, there exist some commands for which an immediate follow-up command exists that is either meant to be used by the command runner or someone else. These include (but are not limited to),

*/files_set (with /files)
*/globalic (with /globalic_pre)
*/party (with /party_invite)
*/party_invite (with /party_join)
*/zone (with /zone_watch)

However, remembering these can sometimes be a bit painful, and given that these are typically used one immediately after the other, it would be nice if some sort of indication was given about how to use them at a moment where it is expected they would be used.

Describe your feature proposal: Given command A whose natural followup is command B, command A's output should include a message on how to use command B. For example,

If /party created party 11037, the OOC output should be (new comment going between **)
You have created party 11037. **Invite others with /party_invite <client_id>**

If you were invited to party 11037, the OOC output should be something like (new comment going between **)
PHANTOM has invited you to join their party 11037. **Accept invitation with /party_join 11037**

If /globalic turned on global IC, the OOC output should be (new comment going between **)
Your IC messages will now be sent to areas 16 through 116. **You can set up a global IC prefix with /globalic_pre**

Describe relevant existing functionality, if any: No command does this at the moment.

Additional comments: No

Additional suggestion: GMs+ entering a zone (or which are part of an area that becomes part of a zone when it is created) are suggested to run /zone_watch to get RP notifications, and to run /zone_unwatch if they leave a zone they are watching. This will help GMs who mistakenly believe will be receiving special notifications just by virtue of being GM to avoid the issue altogether.
