Subject: [PATCH 15/20] fix logic

previously, it was doing:
if (!whitespace and (contains ":" and does not have date format)) OR fails parse

now its doing:
if !whitespace and ((contains ":" and does not have date format) OR fails parse)

this should correctly allow for whitespaces

Subject: [PATCH 17/20] change default height above atmosphere orbit to be 5000
 instead of 20000

if we already tell the user what the minimum value is, then we dont need to set them so high above the atmosphere, as this could just be confusing. 5000 is more than high enough to counteract principia shenanigans, while still allowing the user to be in a low orbit by default
