Eggdrop v1.8.0 Release Candidate 3

We had hoped to avoid it, but in an abundance of caution we have one more Release Candidate in prior to labelling 1.8.0 stable. This one is rather small, but we wanted to give everyone one last chance to shake out the bugs. Special thanks to Erick- and thommey for finding these important but easily overlooked bugfixes:

• Fixed a linking issue when bots are compiled with --disable-TLS
• Various small syntax fixes to catch Eggdrop code up with modern compilers

Once again, we'll give this about two weeks and shoot to release 1.8.0 stable shortly after. Thank you for your support!
