Subject: Validate settings in order in ValidateSettings() (#1475).
X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=9ea8191a050aa2262289a11edde115de1bcb0d71;p=user%2Fhenk%2Fcode%2Finspircd.git

Validate settings in order in ValidateSettings() (#1475).

* Validate the settings in the same order as the parameter syntax
* Always validate Lines and Secs regardless of having a Diff
* Check Backlog for greater than Max as well as being disabled
