title: Create Migration for Column with a Number in the Name
body: <p>I'm porting an app into rails and a couple of the columns are named things like</p>
  
  <p>2nd_phone
  2nd_address</p>
  
  <p>When I try doing a migration using
  t.string :2nd_phone</p>
  
  <p>I get syntax error, unexpected tINTEGER, expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END</p>
  
  <p>Any ideas how to do this in rals?</p>
