Updated Version of HL's QCSG and QBSP

These are new versions of the QCSG and QBSP programs for Half-Life.
Although they are intended to be used with QuArK, they can be beneficial to
map makers using other editors.
<br><br>
These versions support:
<Br><br>
1) QuArK enhanced texture support (QuArK only)<br>
2) Support for floating point map coordinates (all mapping programs)<br>
3) OpenGL is now linked using delayed binding, thus, users who don't have
OpenGL installed on their system will still be able to run the programs.
They just can not use the -opengl command line option. (all mapping
programs)
