Highlights of this patch include:
- Changes will affect SQL Editors in Create dialog boxes, SQL tab of the main screen, Query tool, History entries in the query tool, Query tool opened in New Tab/Window
- All the components of SQL editor will refer to single source of preferences which is cached in the Browser object. All other redundant ajax get preference calls are removed.
- SQL editor will not refer template JS variables anymore, once all the references are removed the template variables will also be removed.
- Code refactoring wherever possible.
- Covered JS test cases wherever possible.
Extract some of the ACI Tree functionalities, and decouple it from the
main source. Also - create some abstractions from the repeated code
around the enable/disable the schema children object create/edit/delete
functionalities, and also created the dialog wrappers for backup and
restore dialogs.

This is the first version of our Tree implementation. At this point is a
very simple tree without no abstractions and with code that eventually
is not very performant, but this is only the first iteration and we are
trying to follow the 'Last Responsible Moment Principle' [1].
Implemention details:
- Creation of PGBrowser.treeMenu
- Initial version of the Tree Adaptor 'pgadmin/static/js/tree/tree.js'
- TreeFake test double that can replace the Tree for testing purposes
- Tests, As an interesting asside because Fake’s need to behave like
the real object you will noticed that there are tests for this type
of double and they the same as of the real object.

- Extract SQLEditor.execute and SQLEditor._poll into their own files and add test around them
- Extract SQLEditor backend functions that start executing query to their own files and add tests around it
- Move the Explain SQL from the front-end and now pass the Explain plan parameters as a JSON object in the start query call.
- Extract the compile_template_name into a function that can be used by the different places that try to select the version of the template and the server type
Note:
1) Once the keyboard shortcut infrastructure is ready we will add generic shortcut to focus out from CodeMirror editor and set foucs to next element, Right now there is no way of doing this, For testing purpose you can manually focus out from CodeMirror and click on data output panel to continue navigate using Tab key.
2) As of now inner panel's are not getting focused on Tab/Shift-Tab keys but once RM#2895 patch gets committed it will start working automatically as it's inherited code which will add tabindex tag automatically on each newly created wcDocker panel.
