Send reports about invalid rules to AdGuard filter maintainers

[Alex-302]

Something like that:

!--- Base filter ---
*string from log 1*
...
*string from log n*
!
!--- Social filter ---
*string from log 1*
...
*string from log n*

or just rules instead of original strings. Target email - filters@adguard.com Sometimes valid rules are marked as invalid, so it will be useful.
