ImageViewer: Enable and disable navigation

Before there was dialogs to indicate if
current file is last or first.

So in this commit, I added functionality to enable
and disable forward and backward navigation based
on if the next file is avialable or not and if the
pervious file is avialable or not, respectively.

ImageViewer: Refactor code and init data

Data intialization was not happening properly, now I did
Initializations properly so that navigation can work from
the very first image.
