Squashed commit of the following:

- Dynamically fall back to PHP API functions to ensure API does always repond even if FTL is not runnung for some reason
- Update PHP API from current devel branch
- Increase flexibility in getQueryTypes API call
- Hide top ads list if nothing to display
- Proper display of activated privacy mode
- Remove spinner (would otherwise not be removed for zero results)
- Update tables every 10 seconds
- Update query types and forward destinations plots every 10 seconds
- More verbose output in top lists (total number next to percentage in tooltip)
- Implemented "recentBlocked" keyword for API
- Ensure compatibility with PHP5 version < 5.4
- Adjust output format of overTimeData10mins to comply with PHP API
- Further speedup of Query Log page by showing only the recent 10 minutes by default
- Hide temperature if FTL is not running and show FTL status
- Add information to Settings page
- Adjust error message when loading of query log failed
- Move processing of domainname, clientIP, clientname and time interval filters for the Query Log page to FTL for speed enhancement
- Generate link if pi.hole comes up in the Top Domains list
- Remove resolve DNS names option - this is now enabled by default (daemon will only do it once per day instead of PHP-API which did it on every reloading of the web interface)
- Add socket timeout of 10 seconds + modification to Settings page since FTL backend supports API_EXCLUDE_CLIENTS filtering with both IP addresses and host names (also mixed)
- Improved Query Log page
