Subject: [PATCH] Better integration of libevent in build system.

Since event.h is not part of tinc, we include it in have.h were all other
system header files are included.  We also ensure -levent comes before -lgdi32
when compiling with MinGW, apparently it doesn't work when the order is
reversed.
