implemented self-documenting (online) help system

 * the new "?" (help) command can be used to look up
   help topics.
 * help topics are index from $SCITECOPATH/women/*.woman.tec
   files.
 * looking up a help topic opens the corresponding "womanpage"
   and jumps to the position of the topic (it acts like an anchor
   into the document).
 * styling is performed by *.woman.tec files.
 * Setting up the Scintilla view and munging the *.tec file
   is performed by the new "woman.tes" lexer.
   On supporting UIs (Gtk), womanpages are shown in a variable-width
   font.
 * Woman pages are usually not hand-written, but generated from manpages.
   A special Groff post-processor grosciteco has been introduced for this
   purpose. It is much like grotty, but can output SciTECO macros for styling
   the document (ie. the *.woman.tec files).
   It is documented in its own man-page.
 * grosciteco also introduces sciteco.tmac - special Troff macros
   for controlling the formatting of the document in SciTECO.
   It also defines .SCITECO_TOPIC which can be used to mark up
   help topics/terms in Troff markup.
 * Woman pages are generated/formatted by grosciteco at compile-time, so
   they will work on platforms without Groff (ie. as on windows).
 * Groff has been added as a hard compile-time requirement.
 * The sciteco(1) and sciteco(7) man pages have been augmented with
   help topic anchors.
