Command hooks [#86]

Browse Source 
* Command API function to addHook(command, callback)
* Commands open to callbacks must return information or indicate failed completion by return false
* Hooks to be added in module onLoad
* Command loop checks for available hooks and return state, then applies with module scope.
* onLoad running moved to end of all module loading to facilitate this without order problems
* Added example for ~qadd dent
