- Changed name from 'Gentellela' to Gentelella on every page including
readme.md and package.json

Rename Gentellela to Gentelella as per #340.

- removed all of the inline JS ( every page it has her own JS )
- created separate functions ( ex: init_chart(); )
- now all of the JS is in one place ( custom.min.js file )

Dynamic tables, search button is not working in responsive design.

- Now search button works just fine on responsive.

This fixes the first menu_section from being too close to the profile div when side-bar is expanded (nav-md).

- Noticed that link #Logout from Sidebar doesn't work so I took care of
it on every page.

Update also fix some following problem:
- Switcher now working
- Datatable header fix example is now working
- Add missing starrr ratings
- Some mobile responsiveness on table.html page
