[BUG] Using the ;help command, without page reference, leads to page NaN of 8.

[iBryguy]

Description

If you use the command ;help, it takes you to help page NaN of 8.

Similarly, although tangentially related, using a help page of 0 or less returns a TypeError in chat as read property '0' is undefined.

Steps to reproduce

1. Open chat.
2. Use command ;help
3. See error.

Expected behavior
Expected that the help page 1 would be displayed, as that is the first of the help pages.
Alternatively, would have been reasonable to have been given information on either ;help <page number> and/or ;help [command: CommandName] and/or ;? [command: CommandName]

Screenshots

;help 1 still works though, right?

Yep, all normal help pages work appropriately. It's a minor issue overall; just thought I'd let you know about it.
