Add new jobs for jenkins

This is for issue #24, I added just jobs for desktop, for mobile if we decide we want to run them to we can just copy the job and add an extra parameter in xshell command. 
Regarding trigger.py, I added just a  plain script with options so it won't throw when called, this will be overwrited by upcoming pr from issue #17.
You should think about which other kind of parameters are needed for a proper reporting of Jenkins.
