usage: update "Making Sopel ignore people" page for 8.x

We don't have "hostmask" blocks any more; only "host". This is part of a
fairly long saga to sane-ify the `.blocks` command:

-Sopel has a built-in ability to ignore specified people. This is managed through the `.blocks` command. Sopel can block by either nickname or hostmask.
+Sopel has a built-in ability to ignore specified users by either nickname or
+hostname. Bot admins can manage Sopel's ignores using the `.blocks` command.
 
-Both the nicks and the hostmasks you give to Sopel use regular expressions. If you're just looking to block a specific name (like you might if you want to block another bot), you don't need to worry about this. Otherwise, refer to [this page](https://docs.python.org/2/library/re.html) for details about the syntax.

-The `.blocks` command is used by giving it one of three different commands: `list`, `add`, and `del`. These list all blocks, add a block, or delete a block respectively. After that, it takes an argument of either `nick` or `hostmask`, indicating whether you want to list/add/delete nick or hostmask blocks. `add` and `del` both take a final argument, the nick or hostmask block that you want to add/delete.
+The `.blocks` command is used by giving it one of the three main
+subcommands—`list`, `add`, and `del`—followed by `nick` or `host` to indicate
+whether you want to list/add/delete nickname or hostname blocks. `add` and `del`
+both require a final argument: the nick or host pattern that you want to
+add/delete.
