Documentation updates (STR #505, STR #513)

The old source file "fl_set_gray.cxx" is not needed (STR #516)

Fl_Text_Display still called delete[] instead of free() in one
place (STR #503)

Fl_File_Chooser didn't correctly call isprint() and isspace()
when checking to see if the current file was text that can be
previewed (STR #517)

FLUID didn't compile with Borland C++ due to a compiler bug (STR
#496)

Fl_Positioner did not handle reversed min and max values (STR
#510)

fl_descent(), fl_height(), and fl_width() would crash a program
if you didn't call fl_font() first; they now return -1 if no
font is set (STR #500)
