Title: Adds getMonthsBetween

This new method allows to compute the number of months between two dates. Example usage:
```javascript
var sDate = new Date( "Feb 28 2013" );
assert.equal( sDate.getMonthsBetween( new Date( "Mar 30 2013" ) ).toFixed( 5 ), 1.09677 );
```
Note that the return value is always a decimal value even if two dates are identical. So the following code will return 0.03571 rather than 0
```javascript
var sDate = new Date( "Feb 28 2013" );
assert.equal( sDate.getMonthsBetween( new Date( sDate.getTime() ) ).toFixed( 5 ), 0.03571 );
```
