Upgrade Tooltip by DistillNote

A cleaner tooltip line, a settings screen and a minimap button.

• A cleaner tooltip line: a gap, then "Upgrade for Arms" with our drop on the left and an arrow and "+0.7%" on the right ("Downgrade for …" and a down arrow for a downgrade, "No change for …" at 0.0%), and "PvE estimate" under it in grey. The word and the arrow say which it is; the colour repeats it.
• Hold Shift: your class's other specs, each with its value; then the slots for rings, trinkets and one-handers, the damage change ("+3.7 DPS of about 808"), and where the numbers come from.
• A new settings screen (the game's options under AddOns, the minimap button, or /dnup). New in it:
  • Import from DistillNote: paste a link or code from our talent calculator, and the addon chooses the spec with the most points. Or type /dnup import <code>.
  • Show the "Shift: more" hint (on), the damage change line without Shift (off), hide changes under 0.1% (off), colour-blind friendly colours (blue and orange, off), and the line on items linked in chat (on).
• A minimap button: click it for the settings, drag it around the minimap's edge. You can hide it in the settings.
• Everything else works as in 1.0.0, with the same defaults.
