The '%' sign is recognized as an escape character in Freelancer's text markup language. Because of this, every percent sign followed by a space in rumors would show up as blank. This commit rectifies that by replacing all '%' signs in rumors with the word 'percent'.
Sometimes the 'Sierra Cloud' was mentioned in Freelancer's text, which is incorrect because Sierra is a field, not a cloud. Given the context, these entries are actually referring to the Tahoe Ice Cloud.
