 - Correct lua api function names in doc
 - always generate backup file when opening file
 - renamed scim to sc-im in Makefile
 - Document trigger return value convention

Issues fixed:
 - fix bug when deleting an ent that for instance has a @sum()... it
   used to remove its vertex and THE ENTS LINKED to THEM!
 - fix error messages when using "scim --version" and color definitions
   are intented to be applied from .scimrc.
 - fix in waiting for valid command to complete after pressing ESC key.
 - fix in parse_str so a word with white space can be stored in
   dictionary value
 - fix when setting default_paste_from_clipboard_cmd
 - Don't clobber startup message w/ err opening file
 - Allow for lua scripts in local .sc directory #259
 - Send informational messages to stderr rather than the output when
   used in non-interactive mode   #263
 - fixed cell_negative color      #271
 - fixed locked cells when saving #261
 - fixed DEL key in insert mode   #272
 - fix when resizing column       #266
 - "Autobackup - case insensitive QER options when backup exists"
 - fixed segfault when fcopy'ing with no selection while on first column
 - Call write triggers on value clear
 - Use sc_info to report trigger exit code
 - fixed #277
 - Grow table up to MAXROWS exactly
 - Remove redundant if clause (God only knows where that was).
 - fix in getVertex that prevented rebuild_graph to work properly.
 - fix annoying bug because of not resetting inputline_pos to 0 when
   confirming a command in COMMAND_MODE
 - fix in let and slet. existing vertexs should not be removed.
 - added "eval_visited" in vertex struct for not to collide with
   current "visited", since:
     EvalAll uses EvalBottomUp
     EvalBottomUp uses EvalJustOneVertex
     EvalJustOneVertex uses eval
     eval uses GraphAddEdge
     GraphAddEdge uses GraphIsReachable
     GraphIsReachable uses visited
     and EvalBottomUp also uses uses visited!
 - Also changed markAllVerticesNotVisited and
   All_vertexs_of_edges_visited functions.
 - Some other issues fixed: #228, #234, #239, #240, #244, #246, #260,
   #295, #308
 - .. and many other fixes and improvements!

Pending:
  The most significative issue is regarding circular references.
  This have to be deeply analyzed and with the collaboration of the
  community
  it would be hopefully fixed by v0.9.
