Merge pull request #46 from daprice/master

Add web clip icons for iOS
Added logging to file on top of to stdout, temperature parsing now can cope with negative temperature (shouldn't normally occur but seems to happen with buggy firmware), added option to wait for "start" response from printer firmware before switching to state "operational" (defaults to previous behaviour)
Added settings dialog for configuring OctoPrint

Warning: Many settings will need a restart of OctoPrint to take effect, adding corresponding notes is still a TODO. There's also no proper validation and error handling yet, so use at your own risk.
