* Do not use fileInfo.get_modification_date_time for compatibility reason.
* Inverse 'Open drawing' list order: recent first.
* Overwrite identical contents when the save operation is queried by the user.
Pointer movement is ignored when the `space` key is held.
To ensure [Screenshot Tool](https://extensions.gnome.org/extension/1112/screenshot-tool/) extension compatibility, we need a way to let the third extension select the screenshot area with pointer but without leaving drawing mode and without drawing.
As a side effect, it allows to insert straight line segments in free drawing (after releasing the key).
Fixes issue #20
St.Entry clutter_text set the DEFAULT cursor on leave event with a delay and overrides the cursor set by area.updatePointerCursor().
In order to update drawing cursor on menu closed, we need to leave the saveEntry before closing menu.
Since escape key press event can't be captured easily, the job is done in the menu close function.
* Use a "drawOnYourScreen" subdir in the xdg user data dir
* Info item with the name of the last saved/open json file
* "Open drawing" sub menu with data dir content
* "Save drawing" sub menu with entry
* "Save", "Open previous" and "Open next" keybindings
* Set 'max-height' property to menu actor.
* Reduce size of menu items.
* Rename 'draw-on-your-screen-menu-separator' style class to 'draw-on-your-screen-menu-separator-item' because it is relative to the item actor, not the item._separator actor.
* Rename 'draw-on-your-screen-separator' style class to 'draw-on-your-screen-helper-separator' not to confuse with menu separator.
* use var to export extensionJs.manager
* remove duplicated (old) buildPrefsWidget
* set OsdWindow.HIDE_TIMEOUT in a try/catch because HIDE_TIMEOUT is not exported with 'var'
* capture i in callbacks in for(){} (i is changing)
* add 3.24 version as supported
