Softbank Ultralink - Defense boost not shown

[thatcode]

2 portals, both with 12 links, show 60 defence bonus from links. This is correct :)

However, 1 of these portals has an SBUL attached, and so should be showing 90 defence bonus from links alone.

Images attached.

Has anybody figured out whether the defense boost stacks? We have the defense boost in mod data, but yeah, it's ignored when calculating mitigation.

The stacking is multiplicative as shown by the screenshot below for two and three SoftBank Ultra Links (1.5 ^ 2 = 2.25 ≈ 2.3 and 1.5 ^ 3 = 3.375 ≈ 3.4 = 2.3 + 1.1).

I've created a pull request #1257 fashioned after the pull request #1243 but by using multiplicative stacking instead of additive stacking to address this issue.
