CS-4766 CS-5558 Fix several issues with translation of support settings and TinyMCE

This pull request fixes several issues outlined in ticket CS-4766...

1. The support settings box was not wide enough for the number of blue buttons we have now, especially when a language is more verbose (e.g. German)

2. Because the words 'Sourcefabric's privacy policy' were within a HTML tag which was not part of the string, they could not be translated

3. The string 'Don't remind me' was not working in YML format because of the apostrophe, it has been changed to 'Do not remind me' as a workaround
