input placeholders are too dark in v3.2.0

Created by: juodumas

#13847 (closed) changed @gray-light from #999 to #777. This change darkened input placeholder colors, so that now it is difficult to discern pre-populated values from placeholders.

This is how it looks with v3.2.0: http://jsbin.com/lohahole This is how it looked with v3.1.1: http://jsbin.com/funecuyu While I prefer at least #A9A9A9, as in Chrome: http://jsbin.com/kafimaya
