fix language tags for Guacamole 1.2.0, workaround for greyed out continue button, add build logging

Build revision and timestamp are logged on start and sent as http request headers on connection to the sat server. (Bwlp-Plugin-Build-Revision and Bwlp-Plugin-Build-Timestamp)
This build now requires guacamole >=1.2.0
