Hyperlink feature in progress

[ryuntalan]

Description of the Pull Request

This Pull Request documents the progress made on Issue #306. A hyperlink command has been created to check for a valid URL and open it in a new tab. The command is implemented in the Context Menu.

What still needs to be worked on is to figure out a way to conditionally open up the context menu to have the hyperlink command be present only when right-clicking on a cell with a valid URL.

Issue being fixed:

Addresses #306

Changes proposed:

• Check for valid URL function
• Open valid URL in a new tab using the context menu
