Internet points tracker

[parsec]

I'd like to bring back our 'ole internet points feature from TheDoctor.

Usage would be:

<nick>++ (adds 1 internet point)
<nick>-- (removes one internet point)
!tips <nick> (shows current user's internet points)

Sample usage:

<m242> parsec++
<bytebot> parsec gained an internet point! parsec has 1 internet point(s)!

<parsec> suser--
<bytebot> suser lost an internet point! suser has -1000 internet point(s)!

<person> !tips parsec
<bytebot> parsec has 1 internet point(s)!
