Title: Make .input-xxlarge responsive

When using the widest form control style (.input-xxlarge), controls
don't adapt to smaller screens. This fixes it and extends the solution
to .input-xlarge controls (they are almost 300px anyway…).

This doesn't solve an existing problem for LANDSCAPE PHONE TO SMALL
DESKTOP & PORTRAIT TABLETS: in this screen sizes, the widest ".span*"
classes and ".input-xxlarge" can still give problems.

Also, is there any reason not to make all input width classes
(".input-xsmall", ".input-small", …) 100%? What is the conceptual
difference between a input.span1 and input.input-xsmall?
