Adds Gas Analyzer (#1591)

* -Started Gas Analyzer
-TemperatureHelpers

* Formatting

* Adds PopupTooltip to NotifyManager

* Revert Tooltip fuckery

* Gas Analyzer gives proper error messages

* Localization

* Added a very wip gas analyzer ui

* UI works, doesn't look good but hey

* Safety checks

* Fancy WIP gas mix bar

* Gas Color

* Gas Amount shows only 2 decimal places

* -Made bar full width
-Moved gas list into a table
-Some gas bar things

* IDropped something

* Description

* -Percentage
-Padding

* ItemStatus

* -Proper Danger Warnings
-Added Warning danger state
