WIP #7

[yugeshk]

I guess similar to the other pull request, you would not approve of this one as well.
My question is what is the point of having things that are under the "mock" folder of the gui-devel branch on the master? Since they are solely for my purpose so that later when I need to merge those widgets into the app I can do that easily by referring to that code.

I know the buttons are blowing up right now - will fix that after the whole work-flow differences are sorted and we start some merges. Also the space to the left is actually two scrollable containers stacked top-bottom for contacts and keys - they can be made clickable (have done a similar mock) and we can include a right-click list of options like delete, certify, uncertify for contacts and delete, split-key for the keys list. Both are to be populated from the gpg directory.
