Split qb64.bas into $included components: notably settings, version, gloabal, ide (& wiki downloader), subs/functions (and extensions including user mods and opengl)
Moved 'user mods' to source\subs_functions\extensions
Removed legacy functionality of the QB64 update system (including compression functions)
QB64.BAS can be compiled independent of its IDE $includes (just comment them out)
QUI commeted out (needs minor revision)
Updated version to 1.000 (just ran out of numbers)
Pushed changes introduced by LUKE (Johny B on the QB64 forums) as follows :
Fixed setup_lnx.sh, added _CWD$, fixed handling of errno.
Converted setup_lnx.sh to Linux line endings (was preventing the script from running).
We now include <errno.h>, so the errno variable actually works - before it was just a regular variable that wasn't being set on error.
Added a _CWD$ function that returns the current working directory. Should work on all 3 systems, but testing is needed on Win/Mac.
Can cause the following runtime errors: 7 (Out of memory), 51 (Internal error).
