#47 gnome 45 support

[aabrame]

Here is an adaptation of the extension for gnome 45. The main changes I've performed are:

• switching to ECMA modules
• getting rid of ExtensionUtils and replacing a lot of global variables by passing the extension object in the constructor
• some minor improvements

All seems to be working, but I didn't perform exhaustive checks. Note that it is not compatible with previous gnome version.

This is great! but there are small problems The settings of extension draw-on-your-screen2@zhrexl.github.com had an error:

Error: GSettings key quicktoggle-disabled not found in schema org.gnome.shell.extensions.draw-on-your-screen

maybe I do a mistake somewhere

@ruvsv I can't reproduce your error. Can you describe the steps you've followed ?

The schema indeed include a quicktoggle-disabled entry. I don't see why it would be missing in the settings.

I have tested around a bit though i mostly use only basic features but anything ive tried has worked with no issues edeavouros arch

The last commit corrects a bug causing an error when disabling the extension.
