Test and validate configuration files at startup

[xakraz]

Like some Unix software, it would be nice to have some preventive "checks" on configuration files at startup or before restarting DNSAgent when running as a service to prevent errors...

you could patch in https://github.com/JamesNK/Newtonsoft.Json and do something like
http://stackoverflow.com/questions/14977848/how-to-make-sure-that-string-is-valid-json-using-json-net
or use the 4.5 stuff that is also listed in that answer.
Another alternative would be to have a rough cascade of regexp that could catch obvious mismatched pairs et cetera.
