arduino moved to a server app
added status field to ModelRegistry
ModelRegistry.status in ScraperBase. it should probably be moved to each individual scraper class (weather doesn't throw the same error types)
moved scraper status to subclasses
/status page. scrapers' statuses fixed
arduino NetworkSensor takes names at initialization; allows setup of laggy sensors
fixed NetworkDHT muxSelect. Still unclear why it was broken.
arduino scraper (maybe) working
handling t=0 in arduino scraper.
Arduino Format_error works; put status page in menu bar; requests timeout
'Time' is the first column in csv downloads
arduino has __unicode__ and is in admin page
Merge branch 'registry-mutant' into app-restructure
