Comment 25 for bug 1489944

Thank you for accepting my plugin.

I skimmed through 'bookmarksbar.py' in rev. 775 and there are some errors in indentation which seemingly occurred during convertion from 4xSpaces to Tabs.

I also added some minor changes to default settings which I think would be more convenient for users:
- Since tooltips are now accessible I set short names to default. So by default bookmarksbar will look like other pathbars in Zim.
- Also now after enabling the plugin for the first time the bar will be visible so people can see it right away without pressing the button.

All changes compared to 775 rev. are in attachement.
