* Implement OS specific information discovery That way it doesn't have to be fetched during polling Also improve discovery process, os is only detected once, in the core module. EXA is the test os, a couple improvements there. * Use local variable, then unset it so we don't pollute. * fix style issues * test and other fixes * attribute update fixes * Update exa data, need new source data * null missing "os" values * fix ftos odd character * fix ftos odd character * only null for new style or we will reset to null every discovery * Move device observer to own class * Handle location, relocate event logging * update exa e7-2 data * update ird test data, apparently unicode is now working. * update Linux ntc, now uses correct icon * Only load all os on the web, also, we can't load existing the the database isn't connected. * only for devices that have a location * revert ftos test data apparently * revert ird
