The member length limit is now long enough that it's unlikely to
hit the cap by accident. An error will still be displayed if you
attempt to perform a message proxy.
Some of the command rewrite changes resulted in the response messages for importing a system being swapped. When importing without an existing system (ctx.System == null), we want to display the "new system" message. Otherwise, show the count added/modified.
A given system can now have up to 1000 members. Within 50 members of that limit, a warning will display whenever a new member is created via the bot. Once the limit is reached, a final warning will appear indicating that no additional members can be created unless members are first deleted. Attempting to create a new member at that point by any method will result in an error message indicating that the limit has been reached.
Respecting this in pk;import required some restructuring to tease apart which members already exist and which ones need to be created prior to creating any members as it seems preferable to fail early and give the user the ability to intervene rather than pushing the system to the member cap and requiring manual deletion of "lower priority" members before others can be created. One consequence of the restructure is that existing members are being read in bulk which is a performance improvement of 25-70% depending on how many switches need to be imported (the more members you have, the more noticeable this is).
Add `toLower()` method to the sorting used in system lists, so members are ordered regardless of if the first letter of their name is upper or lowercase
