Working on platform-independent pathnames for the IMPORT command.
Added 'ospath.c' to base/generic/general for this purpose.
Patched kvalues and sensitivity to use the 'IMPORT "libname";' syntax
instead of 'IMPORT registerfn FROM libname;'.
Fixed pathnames in create.nsi.
Added GPL header to coupla files.
Added quoting to 'IMPORT' syntax in ascParse.y.
Removed 'PackageOption' from Tcl/Tk related Scons options so that missing Tcl/Tk
doesn't cause breakage.
