Finish the package: Fix Project Switch-Restart Bug

It partially fix the issues:

1. SublimeTextIssues#1379 Restore session, does not set the last scroll position after a project change, or sublime restart
2. titoBouzout#23 Scroll sync doesn't work (ST3 3084)

To accomplish it, it move the caret up and down, this way it forces the scroll view to be switched.
This causes the undesired behavior when switching views after the file being loaded or the
project being restored.

To fix this problems, just to perform those operations when the file is loaded for the first time.
This is a problem when Sublime Text just starts because this package is not loaded yet. This way
we need to perform this action at the first time the file is chose/switched to.

I am thinking about to use the forward on_plugin_loaded to perform a for all views, this way I can still use only the forward on_loadto fix the issue postSublime Text` start and keep the scroll issue when switching views.

Finished the first part implementation. Now remains to replace:

        view.run_command( "move", {"by": "lines", "forward": False} )
        view.run_command( "move", {"by": "lines", "forward": True} )

By a actual command to change the view to the current cursor
centered position and re-enable the setting "scroll_past_end": true,.

---

Seconds step is to catch the change project command, and make the are_we_on_the_project_switch_process() return True. And when the project change is complete, make the are_we_on_the_project_switch_process return False and call the plugin_loaded() to fix the views scroll positions.

import sublime
import sublime_plugin

class SampleListener(sublime_plugin.EventListener):
    def on_window_command(self, window, command, args):
        if command == "edit_settings":
            print ("About to execute " + command)

    def on_post_window_command(self, window, command, args):
        if command == "edit_settings":
            print ("Finished executing " + command)

This temporary fix is a priori concluded. It only down side is when opening a new window, not all cloned view will not be properly set due the bug:

1. Event handlers for cloned views get called with the wrong view object sublimehq/sublime_text#1253 Event handlers for cloned views get called with the wrong view object

The commit shows this stated state functionality:

The fix package is already completed, then this can be closed.
