feat(new-board): added a Presentation feature

[kingavatar]

Added a Presentation features which presents canvasboard cards as slides

Added a Presentation feature which utilizes Reveal.js library though which we create slides from cards and do presentations utlizing them. The slides are added in a bootstrap modal which can be then utlized to view and present the slides which are created dynamically everytime for now to present. In future sync of slides and cards should be done using more lazy load approaches to avoid unnessary compuatations. Press F for full screen and ESC for exiting the modal. More UI controls should be added for these operations.
