don't use underscores from resolutions like 1400x1050_60.0 as accelerator keys
[ This was originally reported by chrysn-guest on 2016-02-08 12:06 as issue 315303 on alioth. ]
underscores in resolutions are passed to gtk in a way that it treats them as accelerators (like _File / New _Tab). instead, the underscores should stay visible.
