Make a border around the filter buttons.

[pAditya198]

Instead of button I've used Checkbox they look more classic and also less variables are used.

Review changes are also fixed @aashutoshrathi

[aashutoshrathi]

Add a schedule entry in the navbar which will only be shown when the show is true in Firebase.
Also, the elements are not centered properly in Schedule element.

@aashutoshrathi should I create a new model for schedule because here I'm using the existing data from speakers

[samagragupta]

Make the colour of the checkbox: #00aaf5
Shift the content of the Schedule page at the centre.
