Power Lasers Transparency (#778)

* Render each visible power link only once.

* Set power lasers opacity based on the setting

* Change power laser colors to work better with transparency

* Slightly reducing power laser width

* Change laser color to the original, minor refactoring

* Change power laser opacity setting label

* Add laser opacity setting text to bundles

* Remove "Show Power Lasers" setting as it's redundant (replaced by lasers opacity setting), changing default laser opacity setting to 100%

* Remove "setting.lasers.name" from other bundles
