Missing "miniupnpc/" include paths

[cassiniNMC]

The absence of "miniupnpc/" of the #include lines in net.cpp is incompatible with some of the package managers.

If I understand you correctly you suggest that we should (re)add the path "minipunpnc/" in the includes? I will edit your post a little to clarify.
On windows that caused an issue because the folder is actually called "miniupnpc-1.8/". The object files for miniupnpc should go into a SUBfolder "miniupnpc" within the folder "miniupnpc-1.8/".
The patch for EasyWinBuilder is already available from Bitcoin. If it helps for MAC this change is ok with Windows I guess.
@domob1812 Maybe someone from the Linux side could comment.

Linux distributions vary in miniupnp include paths. In my packages I have solved the problem by invoking qmake with "INCLUDEPATH=/usr/include/miniupnpc" and "make -C src OPENSSL_INCLUDE_PATH=/usr/include/miniupnpc" for the daemon.

@phelixbtc Namecoin failed to build for me with UPNP enabled (Debian Wheezy) after your commit. Since I don't want UPNP anyway, I did just disable it so far, which works well for me. I don't know what exactly the problem is or how to fix it correctly (never tried to find it out due to lack of interest in UPNP).

@pmconrad would it be a problem for you if we would add the paths again?

If anything breaks I'll find a workaround...

@cassiniNMC In EasyWinBuilder I would have to hack around (changing the source file, copying object files or renaming the miniupnpc folder). I wonder how a clean solution to this could look like? Anyway for now I would prefer #ifdef APPLE and leave the other systems alone.

28e7e65 breaks my build on Ubuntu 14.04 as well. I believe rather than explicitly breaking the build on Linux (and OSX?) systems, hacking around EasyWinBuilder's issues is the correct solution. Technically this a hack anyways since the correct include is #include <miniupnpc/*.h> anyways. I'll see if I can help at all on that front.

OK then. #196
