Title: Calc triggers

This pares back the triggers for the Calculator goodie such that it doesn't handle things which look sort of like arithmetic expressions, but are more likely attempts to express some other intent. Particularly:

- skip `0xN`-looking things, because they are probably more interested in hex numbers than seeing that part turned into "0"
- skip things which look like IP4 addresses in CIDR notation
