Controller Crouch, Slide, and Roll

[IrisHydra]

I'm been using controller for Warframe since launch, recently after the melee block not working i go back and double checked my controller mapping.

Although i able to fix the block problem, but now my old "Hold to crouch" got replaced with "Crouch, Slide, and Roll" and I'm not able to change it.

A quick small slide is very impotent for the fast paced play style in Warframe. With that half second of holding just so it won't turn into a roll, have been a serious impact to the game-play.

Place fix it, or at least make a separate option for crouch like the keyboard "Hold to crouch".
