- Add proper error handling in libs/db/query_exec. Uses a catch function after each then to proper capture database errors and report them to the user.
- Add logging the error stack when a database query error occurs.
- Change error message reported in the response when a database query occurs, because the person making the request does not need to know about an internal error in the database.

* Move concurrent query execution into dbExecAll function
* Add custom response formatting through route labels. For each query in the set, there is an associated label, which will then be used to identify the corresponding result in the response JSON object. For example:
	- labels = [ "a", "b" ]
	- querySet = [ squel.select().from('y'), squel.select().from('x') ]
	- response = { "result" : { "a" : { // result for query a }, "b" : { //result for query b } }
