1c26c16065 Improve "Hide" button tool-tip message (Danny-Scott)
Pull request description:
Cleaned up the tool tip text, it looks as though it just got included back in 2014 when the whole section was added.
Changed hide button tool tip within transaction fee settings area from "collapse fee-settings" to "Hide transaction fee settings" to be more user friendly and fit with other tool tips.
