Added ability to copy comments on long pressing them, and entry in the settings to enable/disable it.

I don't think we need a settings option for this feature unless it is causing some performance hit.
We don't want to have a bloated settings menu.

How it works? Is it like description, you can select the area you want, or it copy the whole description?

[harshlele]

it copies the whole comment. i actually wanted to make it so that you can select the text, but the root view of the comment is clickable, so the the textview isn't selectable.

Code looks ok.
