iOS: Make default system font Helvetica
Without a platform theme implementatin we were relying on QCoreTextFontDatabase::defaultFont() to return the system font. This didn't work because it reported the system font that iOS reports, '.Helvetica Neue UI', which is a private font that does not get added to our font database. The result was that we picked the first font in the list of known fonts -- in this case 'Academy Engraved LET'. We now implement QIOSTheme::font(), which takes precedence over the font database's default font, and hard-code the system font to 'Helvetica', since Qt does not yet have the concept of private system fonts.
