Update CppNet from KakCAT

Hi,

I needed to get some shaders working and the wrong lines were driving me mad, so I had a look at CppNet.

It seems one of the problems is that the CPP comments did not count as a line. It was no problem if there were no #includes, but once you included a file, the #line set by CppNet to say the processor it was again in the original file was way off.

I've directly added a line into the cppcomment although I not sure where the correct place to add the new line is. The code is just a disaster, so I'm afraid of touching anything and doing it worse, so I just patched the problem with the cppcomment. (I'm sure more problems are there because of the way of handling the line count)

I also added the fix @tanis2000 mentioned, otherwise the #include counted one extra CR.

So, in example to reproduce the problem:

// line 1
// line 2
// line 3
// line 4
error
was correctly giving error in line 5 but

// line 1
// line 2
// line 3
error
was giving error in line 3 (actually should give line 2, but the second bug incremented it)

The changes are here: https://github.com/KakCAT/CppNet

I've tested it with my shaders and Kosmonaut's Deferred Engine, but other than that, should be tested just in case my test set is too small and does things worse for other shaders.
