Advanced Atmosphere Tools v1.1.0

• Added a new "atmosphereIsToxic" config option that, when set to "true" and when applied to a body with an oxygenated atmosphere, will make kerbals unable to breathe in the atmosphere, while letting jet engines function unimpeded.
• Added the ability to customize the message displayed when attempting to remove the helmet when the atmosphere is listed as "Toxic" using a config option named "atmosphereIsToxicMessage".
• Fixed a broken extension method that would lead to incorrectly-applied wind vectors.
