LexiconWebService release 1

The lexicon web service release 1 is live fixes OpenSourceFieldlinguistics/FieldDB#1051 !

Whats new:
* changed the port on elasticsearch to 3195 because we currently need to have both it and the lexicondev nodejs accessible client side. 
* added a dns for searchdev and search and pointed them to 3195
* moved the search.js in the public urls to the libs folder (see FieldDBWebServer)
* used the existing bash scripts to turn the service on and off and switch between deploy targets
* moved search and corpus config options into a  lib file for different deploy targets

Whats left:
* eliminate the client side access to searchdev
* use environ vars to control the deploy targets for lexiconwebservice
* for now until we solve the utf8 bug OpenSourceFieldlinguistics/FieldDB#1042, we should hard code which pouches can be searched 

Tested:
* user can index a corpus
* user can search a corpus
