New script: NAV - POLI TEMP

It is what it sounds like. Resolves #189.
Updated Power Pads

The General/Sups Nav now has the new POLI/TEMP script, as well as the
group boxes from the all scripts (no nav) pad. Also, I'm now using
Calibri 8 for the group boxes, instead of 9 (as a result, updated main
pad to match nav pads).
