8120b380bb Introduced a event manager for the browser, which will generate certain
known events, when any activity happens on the browser layout.

The following types of events will be triggered through the browser
event manager.
- pgadmin-browser:frame:* [1]
- pgadmin-browser:frame-<name>:* [1]
- pgadmin-browser:panel:* [1]
- pgadmin-browser:panel-<name>:* [1]
- pgadmin-browser:panel
- pgadmin-browser:frame
- pgadmin-browser:tree
- pgadmin-browser:tree:* [2]

[1] The '*' denotes some of the events generated by the wcDocker, which
    can be useful to do some operations.
	These events are:
	+ wcDocker.EVENT.UPDATED
	+ wcDocker.EVENT.VISIBILITY_CHANGED
	+ wcDocker.EVENT.BEGIN_DOCK
    + wcDocker.EVENT.END_DOCK
	+ wcDocker.EVENT.GAIN_FOCUS,
	+ wcDocker.EVENT.LOST_FOCUS
	+ wcDocker.EVENT.CLOSED
	+ wcDocker.EVENT.BUTTON
	+ wcDocker.EVENT.ATTACHED
	+ wcDocker.EVENT.DETACHED
	+ wcDocker.EVENT.MOVE_STARTED
	+ wcDocker.EVENT.MOVE_ENDED
	+ wcDocker.EVENT.MOVED
	+ wcDocker.EVENT.RESIZE_STARTED
	+ wcDocker.EVENT.RESIZE_ENDED
	+ wcDocker.EVENT.RESIZED
	+ wcDocker.EVENT.SCROLLED

[2] The '*' denotes all the events generated by the Browser Tree
    (aciTree).

The extension modules can utilize these events to do some operations on
nodes, and panels.

This patch includes showing 'Reversed Engineered Query' for the selected
node (if allowed) using the above approch.

The ShowNodeSQL module looks for two events.
1. SQL Panel Visibility change.
   - Based on the visibility of that panel, we start/stop listening the
	 node selection event.
2. Node Selection in Browser tree
   - Based on the selected node type, it will look for 'hasSQL'
	 parameter of the node, and fetch the Query from the server, and
	 show it in the SQL editor.

e27e39a8f3 Added support for the infrastructure for on demand access/create the
server connection.

The BaseDriver and BaseConnection are two abstract classes, which allows
us to replace the existing driver with the currently used. The current
implementation supports to connect the PostgreSQL and Postgres Plus
Advanced Server using the psycopg2 driver.

eb6580b43a Introduced a PgAdmin class inherited from the Flask, which looks for
submodules inherited from the PgAdminModule instead of regular
Blueprint. This allows us to load the module automatically from the
under the pgadmin directory, and will work to extend the pgAdmin
extension module.

PgAdminModule is inherited from the Blueprint, and bring several
methods:
-  get_own_stylesheets, which returns the stylesheets used by the module
   (excluding its submodules stylesheets)
- get_own_javascripts
- menu_items, which returns a dictionray mapping the old hook names
  (context_items etc) to a list of MenuItem instances

For more specialized modules (as for now, any module that should be part
of the browser tree construction), one can define an abstract base class
defining additional methods.

For example, the BrowserPluginModule abstract base class defines the
following methods:
- jssnippets
- csssnipeets
- node_type
- get_nodes

fe834d1ed2 Re-organise node structure and loading to make things somewhat more
simple. This also adds the ability to display servers on the treeview.
