More documentation updates...

Fl_File_Chooser did not handle some cases for filename
completion (STR #376)

Fl_Help_View didn't properly compute the default maximum width
of the page properly, resulting in non-wrapped text in table
cells (STR #464)

Fl_Text_Editor no longer tries to emulate the Emacs CTRL-A
shortcut to move to the first column, since there is a key for
that and the widget does not emulate any other Emacs keys (STR
#421)

Fl_File_Chooser always disabled the OK button when the user
pressed DELETE or BACKSPACE (STR #397)

Added Fl_Browser::swap() methods (STR #459)
