Neil Fraser 2f2252f588 Rename variableDB_ to nameDB_
There is significant confusion in names and comments with regards to variables and procedures.  `Blockly.Generator.prototype.variableDB_` is a Blockly.Names database, not a variable map.  This rename introduces a getter and setter so deprecated references still work.  This commit also fixes some comments which are either outright wrong or misleading regarding variable and procedure names.
