* Added syntax highlighting for mat2, mat3, mat4 and int datatypes

* Added bool data type for syntax highlighting

It forces real nWidth and nHeight and also resets settings sizes accordingly.

config.json will take care of this from now on.

* Change Linux font path if required

* Make the font paht choice at run (and not compilation)

* Fix (I hope so) win64 construction

* Downgrade c++ version

* Seems that all C++ version are unable to convert string to char *...

* Use a C-like file existence check and remove uneeded #ifndef

* Still a blind tentative to compile on windows

Add clipboard support for X11

also fix bug in cmake that was somehow syntactically correct (hurr)

# Conflicts:
#	CMakeLists.txt
#	src/main.cpp

This has been scaring the shit out of me for ages and has to stop.

Support mouse scrolling.

Fixes #27
The minor drawback is that it doesn't take the horizontal text limit into account when scrolling to the right.
One can keep scrolling WAAAAAY after all chars have disappeared to the left.
