Description:
This pull request adds the NetworkAwareness tab to the application which displays one tab for the users' machine information and another tab to generate a QrCode through a provided VCard.

Changes Made:

1. Added a new tab named "NetworkInfo" to the views folder that houses the NetworkInfo and QrCode components which are housed in the "network" folder
2. Added a "NetworkIcon" svg to the icons folder that is shown on the sidebar to navigate to the "NetworkInfo" component
3. Added "getHostName" and "getLocalIp" methods to the preload.js file to load up the app with the users' data on the launch of the app.
4. Added "network" route to router/index.js

Testing:
I have tested the app and building the project using "npm run build" returns a green check of "built"
