#175 adds snap packaging and #177 enabled edge autobuilds:

$ sudo snap install gitless  --edge --devmode
$ gitless.gl

However, all features were too big for the first PR. so here is the list that needs to be polished:

• [ ] expose executable as gl
• [ ] make sure it can access dirs in home
• [ ] make sure it can access any current dir
• [ ] write build manual
• [ ] pass the publishing rights to @sdg-mit
