Update the Copyright section

[kdidenko]

The current 1.1.14 version of "Copyright" section at the TabSaver's dialog pop-up footer has no logical structure.

Beside this, it contains direct links to the TabSaver's Chrome Webstore page along with its registered domain URL, which makes it difficult to track from point of view of links campaign analytics.

Therefore, the following structure changes are required:

• 1. keep the Copyright's Year always up to date (e.g.: © 2014 - current)
• 2. make the logical Copyright sentence structure (e.g.: Copyright © {FROM} - {TO} by TabSaver Team)
• 3. Use shortened Goo.gl URLs followed by Google Analytics campaign tracking parameters for advanced transitions tracking.
• 4. Replace the Chrome Webstore Details page with Chrome Webstore's Review page in order to increase the number of Users Feedbacks
