Improve dmsgweb (#266)

* do not serve redundantly on local port with dmsg web srv

* split up dmsgweb source code into multiple files ; make dmsg web srv able to proxy multiple ports over dmsg

* log fatal error if same number of dmsg ports and local ports are not specified

* make format ; update Makefile

* handle raw tcp connections

* make dmsgweb work with multiple ports ; change everything to arrays or slices
