Beatmap length/play time display in mod select

[Tenexxt]

I personally think that drain time and/or total lenght of the map should be displayed in the mod select menu.
I find the lenght of a map an important enough stat to be shown in the mod select, as it would be very helpfull with mods that affect time, since you could know how long is the map directly instead of having to guess because the game only gives you the NM value.
Tho i have to admit, that im not sure how it would work for WU and WD, and especially AS, but In My Opinion i think giving it to the main 4 (DC, HT, DT, NC) would be fine, but let me know what you think.
