Hi
Please find the attached patch patch with following changes:
1) Implemented CodeMirror addon 'simplescrollbars'.
2) The CodeMirror instance of query tool was not rendering into wcDocker's 'pg-panel-content' div. it renders outside the div, due to which it took little more time investigating why scrollbars doesn't appear in editor.
3) Add new css specific to query tool.
Please review.
Thanks,
Surinder Kumar
