Fixed below review comments

- Removed the "lineWrapping" option from the codemirror textarea because
  it was creating issue in the code folding.
- Handle the values while depositing during debugging.
- Properly handle the Array values while saving it to sqlite database
  and displayed in input dialog.
- SQL code folding was not supported in codemirror so added the same.
