Fix scroll wheel on Linux; tidy up licensing info; clean up Windows setup; fix OSX script permissions.

The scroll wheel now behaves correctly on Linux. Reports suggest that the fix does not have any effect
on OSX though. The licensing documentation is updated to reflect the fact that there are no GPL components
included in a QB64 program. Some redundant code was removed from the Windows setup script. OSX setup and
run scripts were missing the executable bit - hopefully the repository will preserve that change.

 === IMPORTANT LICENSING NOTE FOR QB64 PROGRAMMERS ===
-All executables created with QB64 are subject to the LGPL licence conditions.
+All executables which perform any kind of sound operation are subject to the LGPL license (due to incorporation of mpglibdll and OpenAL).
-All executables which read sound files are subject to the GPL license as well (due to incorporation of libsamplerate).
+Other components are licensed under various permissive licences.
-When distributing your program as an executable all license requirements can be met by:
+When sound components are included (thus the LGPL is in effect), the easiest way to meet terms of the LGPL is to make your program's source code (.BAS) available.
-i) Making your program's source code (.BAS) available and declaring it to be GPL as well as
+If you are not using sound components, you do not need to release the program's source.
-ii) Including this entire license folder distributed with QB64
+If you are using fonts, you are bound by the terms of FreeType's license. Somewhere in your software package should include a notice that your program includes the FreeType library (see licence_freetype_ftl.txt for details)
-It should be noted that the above is not the sole method one could use to abide by the license conditions
+In all cases, you should distribute the LICENSE folder with your program.
-and that creating closed source QB64 programs is possible when LGPL (not GPL) code is dynamically
+
-linked to, not embedded within your executable.
+It should be noted that providing source code is not the only way to meet the conditions of the LGPL (eg dynamic linking) but it is by far the easiest from a technical point of view at this current time.
