debug on Dorsal

this is an initial approach to having debugging information in dorsal. 

1) yes, it uses a `console.log` and `console.timer` but is intended for developers. 

2) to turn it on we can just do `Dorsal.DEBUG = true`

3) is only affecting the actual _runPlugin and the setTimeout wraping `_wireElement` function , my idea is deciding where and what should be the next messages. 
Could we not space things this way? We don't like the column aligned comments. They are hard to maintain.
