JR Timestamp to Date - Epoch Converter

As developers we need to "translate" unix timestamp to more simple read... yes, I mean in "human readable" way... I mean, date and time.

It works by two ways:

1) select text of the web, click on right mouse button and if it is a timestamp (in seconds) the extension will popup the date on screen, click anywhere to close pop.

2) If you have a timestamp on the clipboard, you could click on the extension icon and voilá, you get the date.

I´m thinking in some improvements, do you have any?

I hope you enjoy.
