'In private...' reminder instead of 'In $nick'.
Reformat: Add missing blank lines for readability.
Reformat: Convert to same-line-braces[1].

[1] Experimentally...

I normally prefer to have braces on their own lines (so they line up
horizontally), but I've kind of been giving it a try with them on the
same line as the respective statement since that is apparently the
preferred style by the Perl community (they also apparently do it in the
Linux kernel so it might not hurt to get used to it). I'm on the fence
about it right now. I don't like it, but I don't mind it, and bleh. So
this commit changes Bambot into it for now. It should make the code a
bit more vertically terse (for better or worse), and I guess I'll have
to see how I find maintaining it like this. Worst case I should be able
to reverse patch this to go back. >:(
Reformat: Wrap a couple of line lines.
Refactor: Default constants for nick/user/username.
Reformat: Revise hash ref constructor indentation.
Refactor: Remove some unused junk lines.
Refactor: Turn an ugly map BLOCK into an EXPR.
Add a reminder comment for later refactoring...
Refactor: Normalize if/else into single statement.
Reformat: Move MAIN loop label to first column.
Refactor: Join shortened statement onto one line.
Reformat: Normalize control statements spacing.

I generally hate to see control statements (particularly ones that
require parenthesis for their conditions, etc.) having a space between
the statement keyword and conditions/whatever. The way that for works in
Perl have sort of loosened me up on that and I typically end up doing a
for with a space whether or not there's an explicit loop variable or
not, but I still generally avoid doing this with other statements that
don't support a variable between the keyboard and the condition.
Evidently I've mistakenly done a that few times though so here I am
cleaning it up. >:(
