Fix/autoconnect casesensitive

22:06:52 < phy1729> If I put an autoconnect block in my links.conf it keeps trying to reconnect even when already connected? How can it be configured to only reconnect then stop tryping?  Using  InspIRCd-2.0.5(r0)

22:09:28 < phy1729> Does capitalization matter?

Turned out, it DID matter.
