GitLab

Detail:

• Rewrite Makefile to use shared makefile fragments
• Uses modgen to create the !Alarm module, which obsoletes some source files
• Rename a couple of resource files to match their names when installed
• All the files in Resources:$.Apps.!Alarm are now registered by the !Alarm module, so you can kill or unplug the module to hide it
• The Code blob used to be installed in ResourceFS both by the Messages module and by the !Alarm module - now de-duplicated (only in Messages)
• Consolidate .gitignore files
• Enable GitLab CI
