New Ticking Interface: Grade Feedback in YDS should offer "YDS detailed"

[rouletout]

When ticking a route in YDS that is just graded in "YDS rough" like 5.10 or 5.10+ the grade feedback suggests only grades of the same YDS scale whereas it would be desirable to collect more fine grained feedback (at least optionally) like 5.10c or 5.10d.
