New issue 169 by krustev....@gmail.com: Check a cell with certain name
exists
http://code.google.com/p/toped/issues/detail?id=169

We need a tell function reporting whether a cell with certain name exists
in the db.
Possibly - the existing functions for open/edit cells can be revisited and
updated with options like:
- create if not existing
or simply make the functions return a status - like:
- can't create - it's existing
- can't open - it's not existing

Updates in r2437.

New function added:
bool checkcell(string cell_name, bool editable);

if (editable)
return true if cell_name exists and is editable (i.e. not a library cell)
else
return true cell_name exists

Also:
opencell now returns true on success
newcell now return false if the cell with this name already exists
