[revIgniter] revIgniter and LC8

[Ralf Bitter]

Sorry for coming late. The superfluous "then" keyword in
system/libraries/Input.lc -> _rigValid_ipv4() was overlooked
because server engine versions prior to 8 were forgiving and
didn't complain.
The bug is fixed since version 1.7.2. So, all of you who use
older versions need to fix this in case you intend to upgrade
the server engine to version 8.
Anyhow I recommend to update revIgniter to the latest version.


Warm regards

Ralf
