First phase refactoring the JOIN class:
* Pulled out the init() method
* Created proper, ordered initialization list for JOIN constructor
* Initialized all member variables in initialization list (this will enable us to move towards using new for JOIN properly)
* Moved member variables around in the class to fit more-frequently accessed attributes
in the first part of the class, which should fix some of the large number of I2mr and D2mr
cache misses I've found in JOIN::optimize() and JOIN::prepare.
* Style cleanup
