Character Creator fixes and Improvements

[MaxIsJoe]

fixes #10195
Briefly touches upon #7878

Known Issues:

• Some dropdowns have their captions disappear for no apparent reason. This is just a visual oddity and is not game breaking in any way.
• The dropdowns in the info page do not follow the exact color scheme of the dropdowns in the appearance page.
• Navigation buttons always have padding at the top for some reason, and they cannot be overridden.
