Windows Build with UPX Packer

[hollesse]

Our windows build is just a normal Go build. It seems that the normal Go Build can be a cause for virus detection to think mob is malicious. Therefore we should test if packing the windows executable with UPX mitigates this Issue.

We should start with packing it locally with UPX and send it to @jakewilliami so he can check if some of the Issues mentioned here (#357) If this fixes some of the issues we should add the UPX packing to our Buildpipeline.
