Fails to build on Ubuntu 12.04 LTS with znc/IRCNetwork.h: No such file or directory

[mgedmin]

The README claims support for ZNC versions as old as 0.078. Ubuntu 12.04 LTS comes with znc 0.206. When I try to build there, I get the following error:

$ sudo apt-get install znc-dev libcurl4-openssl-dev
$ make curl=yes
sed -i -e "s|PUSHVERSION \".*\"|PUSHVERSION \"v1.0.0-46-g20d3f02-dirty\"|" push.cpp
CXXFLAGS=" -DUSE_CURL -lcurl" LIBS=" -DUSE_CURL -lcurl" znc-buildmod push.cpp
Building "push.so" for znc 0.206... push.cpp:17:28: fatal error: znc/IRCNetwork.h: No such file or directory
compilation terminated.
[ !! ] Error while building "push.so"
make: *** [push.so] Error 1

Looks like 6c413a9 broke compatibility with older znc versions.

As mentioned in #77 and the readme, building on ZNC version 0.206 or older requires using the "legacy" branch of znc-push.
