Alpha Release - TxtNet Browser 2.0

This release includes many new changes, with the headlining feature being the ability to host your own TxtNet Server instance through the app using your phone's own phone number. Minor improvements have also been made to the TxtNet Client experience, mostly in the backend. Major frontend overhauls are still to come; feel free to submit a pull request if you are interested in helping to develop this project! A more comprehensive changelist will be provided soon. As this is an alpha release, expect many bugs. Please report them in the issues tab.

NOTE: A default server phone number is not currently provided. Soon, I will host a server on a +1 country code number and provide it to users for testing.
