my own rc.lua, copied from rc.lua.multicolor

- use gnome-terminal
- use chromium as browser
- rules to automagically put apps into tags
- Remove weather/yawn.widget
- use media keys for volume -/+/mute
- amixer: use card #1 (card #0 is not used on my t440p)
- lua: access tags by name: tag["the name"] stores the index of tags.names (name -> index)
