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.

Thanks to all that helped and created PR.
Thanks to all who support and use this program.
